DESCRIPTION
The MPY634 is a wide bandwidth, high accuracy, four-
quadrant analog multiplier. Its accurately laser-trimmed
multiplier characteristics make it easy to use in a wide
variety of applications with a minimum of external parts,
often eliminating all external trimming. Its differential X, Y,
and Z inputs allow configuration as a multiplier, squarer,
divider, square-rooter, and other functions while maintain-
ing high accuracy.
The wide bandwidth of this new design allows signal
processing at IF, RF, and video frequencies. The internal
output amplifier of the MPY634 reduces
design complexity compared to other high frequency mul-
tipliers and balanced modulator circuits. It is
capable of performing frequency mixing, balanced modula-
tion, and demodulation with excellent carrier rejection.
An accurate internal voltage reference provides
precise setting of the scale factor. The differential Z input
allows user-selected scale factors from 0.1 to 10 using
external feedback resistors.

THEORY OF OPERATION
The transfer function for the MPY634 is:
VOUT = A – (Z1 – Z2)
where:
A = open-loop gain of the output amplifier (typically
85dB at DC).
SF = Scale Factor. Laser-trimmed to 10V but adjustable
over a 3V to 10V range using external resistors.
X, Y, Z are input voltages. Full-scale input voltage
is equal to the selected SF. (Max input voltage =
±1.25 SF).
An intuitive understanding of transfer function can be gained
by analogy to the op amp. By assuming that the open-loop
gain, A, of the output operational amplifier is infinite,
(X1 – X2) (Y1 – Y2)
SF
inspection of the transfer function reveals that any VOUT can
be created with an infinitesimally small quantity within the
brackets. Then, an application circuit can be analyzed by
assigning circuit voltages for all X, Y and Z inputs and
setting the bracketed quantity equal to zero. For example,
the basic multiplier connection in Figure 1, Z1 = VOUT and
Z2 = 0. The quantity within the brackets then reduces to:
– (VOUT – 0) = 0
This approach leads to a simple relationship which can be
solved for VOUT to provide the closed-loop transfer function.
The scale factor is accurately factory adjusted to 10V and is
typically accurate to within 0.1% or less. The scale factor
may be adjusted by connecting a resistor or potentiometer
between pin SF and the –VS power supply. The value of the
external resistor can be approximated by:

RSF = 5.4kΩ
Internal device tolerances make this relationship accurate to
within approximately 25%. Some applications can benefit
from reduction of the SF by this technique. The reduced
input bias current, noise, and drift achieved by this technique
can be likened to operating the input circuitry in a higher
gain, thus reducing output contributions to these effects.
Adjustment of the scale factor does not affect bandwidth.
The MPY634 is fully characterized at VS = ±15V but
operation is possible down to ±8V with an attendant reduc-
tion of input and output range capability. Operation at
voltages greater than ±15V allows greater output swing to be
achieved by using an output feedback attenuator (Figure 1).
As with any wide bandwidth circuit, the power supplies
should be bypassed with high frequency ceramic capacitors.
These capacitors should be located as near as practical to the
power supply connections of the MPY634. Improper by-
passing can lead to instability, overshoot, and ringing in the
output.

BASIC MULTIPLIER CONNECTION
Figure 2 shows the basic connection as a multiplier. Accu-
racy is fully specified without any additional user-trimming
circuitry. Some applications can benefit from trimming of
one or more of the inputs. The fully differential inputs
facilitate referencing the input quantities to the source volt-
age common terminal for maximum accuracy. They also
allow use of simple offset voltage trimming circuitry as
shown on the X input.
The differential Z input allows an offset to be summed in
VOUT. In basic multiplier operation, the Z2 input serves as
the output voltage ground reference and should be connected
to the ground of the driven system for maximum accuracy.
A method of changing (lowering) SF by connecting to the
SF pin was discussed previously. Figure 1 shows an alterna-
tive method of changing the effective SF of the overall
circuit by using an attenuator in the feedback connection to
Z1. This method puts the output amplifier in a higher gain
and is thus accompanied by a reduction in bandwidth and an
increase in output offset voltage. The larger output offset
may be reduced by applying a trimming voltage to the high
impedance input, Z2.
The flexibility of the differential Z inputs allows direct
conversion of the output quantity to a current. Figure 3
shows the output voltage differentially-sensed across a se-
ries resistor forcing an output-controlled current. Addition
of a capacitor load then creates a time integration function
useful in a variety of applications such as power computa-
tion.
SQUARER CIRCUIT (FREQUENCY DOUBLER)
Squarer, or frequency doubler, operation is achieved by
paralleling the X and Y inputs of the standard multiplier
circuit. Inverted output can be achieved by reversing the
differential input terminals of either the X or Y input.
Accuracy in the squaring mode is typically a factor of two
better than the specified multiplier mode with maximum
error occurring with small (less than 1V) inputs. Better
accuracy can be achieved for small input voltage levels by
reducing the scale factor, SF.
DIVIDER OPERATION
The MPY634 can be configured as a divider as shown in
Figure 4. High impedance differential inputs for the numera-
tor and denominator are achieved at the Z and X inputs,

respectively. Feedback is applied to the Y2 input, and Y1 is
normally referenced to output ground. Alternatively, as the
transfer function implies, an input applied to Y1 can be
summed directly into VOUT. Since the feedback connection
is made to a multiplying input, the effective gain of the
output op amp varies as a function of the denominator input
voltage. Therefore, the bandwidth of the divider function is
proportional to the denominator voltage (see Typical Perfor-
mance Curves).

FIGURE 4. Basic Divider Connection.
Accuracy of the divider mode typically ranges from 1.0% to
2.5% for a 10 to 1 denominator range depending on device
grade. Accuracy is primarily limited by input offset voltages
and can be significantly improved by trimming the offset of
the X input. A trim voltage of ±3.5mV applied to the “low
side” X input (X2 for positive input voltages on X1) can
produce similar accuracies over 100 to 1 denominator range.
To trim, apply a signal which varies from 100mV to 10V at
a low frequency (less than 500Hz). An offset sine wave or
ramp is suitable. Since the ratio of the quantities should be
constant, the ideal output would be a constant 10V. Using
AC coupling on an oscilloscope, adjust the offset control for
minimum output voltage variation.
SQUARE-ROOTER
A square-rooter connection is shown in Figure 5. Input
voltage is limited to one polarity (positive for the connection
shown). The diode prevents circuit latch-up should the input
go negative. The circuit can be configured for negative input
and positive output by reversing the polarity of both the X
and Y inputs. The output polarity can be reversed by revers-
ing the diode and X input polarity. A load resistance of
approximately 10kΩ must be provided. Trimming for im-
proved accuracy would be accomplished at the Z input.

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

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.
