DESCRIPTION
The INA117 is a precision unity-gain difference
amplifier with very high common-mode input voltage
range. It is a single monolithic IC consisting of a
precision op amp and integrated thin-film resistor
network. It can accurately measure small differential
voltages in the presence of common-mode signals up
to ±200V. The INA117 inputs are protected from
momentary common-mode or differential overloads
up to ±500V.
In many applications, where galvanic isolation is not
essential, the INA117 can replace isolation amplifiers.
This can eliminate costly isolated input-side power
supplies and their associated ripple, noise and quies-
cent current. The INA117’s 0.001% nonlinearity and
200kHz bandwidth are superior to those of conven-
tional isolation amplifiers.
The INA117 is available in 8-pin plastic mini-DIP and
SO-8 surface-mount packages, specified for the –40°C
to +85°C temperature range. The metal TO-99 models
are available specified for the –40°C to +85°C and
–55°C to +125°C temperature range.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.

APPLICATION INFORMATION
Figure 1 shows the basic connections required for operation.
Applications with noisy or high-impedance power-supply lines
may require decoupling capacitors close to the device pins.
The output voltage is equal to the differential input volt-
age between pins 2 and 3. The common mode input
voltage is rejected.
Internal circuitry connected to the compensation pin 8 can-
cels the parasitic distributed capacitance between the feed-
back resistor, R2, and the IC substrate. For specified dy-
namic performance, pin 8 should be grounded or connected
through a 0.1µF capacitor to an AC ground such as V+.
COMMON-MODE REJECTION
Common-mode rejection (CMR) of the INA117 is depend-
ent on the input resistor network, which is laser-trimmed for
accurate ratio matching. To maintain high CMR, it is impor-
tant to have low source impedances driving the two inputs.
A 75Ω resistance in series with pin 2 or 3 will decrease CMR
from 86dB to 72dB.
Resistance in series with the reference pins will also degrade
CMR. A 4Ω resistance in series with pin 1 or 5 will decrease
CMRR from 86dB to 72dB.
Most applications do not require trimming. Figures 2 and 3
show optional circuits that may be used for trimming offset
voltage and common-mode rejection.
TRANSFER FUNCTION
Most applications use the INA117 as a simple unity-gain
difference amplifier. The transfer function is:
VO = V3 – V2
V3 and V2 are the voltages at pins 3 and 2.

MEASURING CURRENT
The INA117 can be used to measure a current by sensing the
voltage drop across a series resistor, RS. Figure 4 shows the
INA117 used to measure the supply currents of a device
under test. The circuit in Figure 5 measures the output
current of a power supply. If the power supply has a sense
connection, it can be connected to the output side of RS to
eliminate the voltage-drop error. Another common applica-
tion is current-to-voltage conversion, as shown in Figure 6.

In all cases, the sense resistor imbalances the input resistor
matching of the INA117, degrading its CMR. Also, the input
impedance of the INA117 loads RS, causing gain error in the
voltage-to-current conversion. Both of these errors can be
easily corrected.
The CMR error can be corrected with the addition of a
compensation resistor, RC, equal in value to RS as shown in
Figures 4, 5, and 6. If RS is less than 20Ω, the degradation
in CMR is negligible and RC can be omitted. If RS is larger
than approximately 2kΩ, trimming RC may be required to
achieve greater than 86dB CMR. This is because the actual
INA117 input impedances have 1% typical mismatch.
If RS is more than approximately 100Ω, the gain error will
be greater than the 0.02% specification of the INA117. This
gain error can be corrected by slightly increasing the value
of RS. The corrected value, RS', can be calculated by:
RRk
kR
SS
S
'–
=•Ω
Ω
380
380
Example: For a 1V/mA transfer function, the nominal,
uncorrected value for RS would be 1kΩ. A slightly larger
value, RS' = 1002.6Ω, compensates for the gain error due to
loading.
The 380kΩ term in the equation for RS' has a tolerance of
±25%, so sense resistors above approximately 400Ω may
require trimming to achieve gain accuracy better than 0.02%.
Of course, if a buffer amplifier is added as shown in Figure
7, both inputs see a low source impedance, and the sense
resistor is not loaded. As a result, there is no gain error or
CMR degradation. The buffer amplifier can operate as a
unity gain buffer or as an amplifier with non-inverting gain.
Gain added ahead of the INA117 improves both CMR and
signal-to-noise. Added gain also allows a lower voltage drop
across the sense resistor. The OPA1013 is a good choice for
the buffer amplifier since both its input and output can swing
close to its negative power supply.

Figure 8 shows very high input impedance buffer used to
measure low leakage currents. Here, the buffer op amp is
powered with an isolated, split-voltage power supply. Using
an isolated power supply allows full ±200V common-mode
input range.
NOISE PERFORMANCE
The noise performance of the INA117 is dominated by the
internal resistor network. The thermal or Johnson noise of
these resistors produces approximately 550nV/√Hz noise.
The internal op amp contributes virtually no excess noise at
frequencies above 100Hz.
Many applications may be satisfied with less than the full
200kHz bandwidth of the INA117. In these cases, the noise
can be reduced with a low-pass filter on the output. The two-
pole filter shown in Figure 9 limits bandwidth to 1kHz and
reduces noise by more than 15:1. Since the INA117 has a
1/f noise corner frequency of approximately 100Hz, a cutoff
frequency below 100Hz will not further reduce noise.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
