Their two-op-amp design provides excellent performance with very low quiescent current (175A/channel). This, combined with a wide operating voltage range of 1.35V to 18V, makes them ideal for portable instrumentation and data acquisition systems. Gain can be set from 5V/V to 10000V/V with a single external resistor. Laser trimmed input circuitry provides low offset voltage (250V max), low offset voltage drift (3V/C max) and excellent common-mode rejection. Single version package options include 8-pin plastic DIP, SO-8 surface mount, and fine-pitch MSOP-8 surface-mount. Dual version is available in the space-saving SSOP-16 finepitch surface mount, SO-16, and 16-pin DIP. All are specified for the -40C to +85C industrial temperature range.

Low resistor values required for high gain can make wiring resistance important. Sockets add to the wiring resistance, which will contribute additional gain error in gains of approximately 100 or greater. Figure 1 shows the basic connections required for operation of the INA126. Applications with noisy or high impedance power supplies may require decoupling capacitors close to the device pins as shown. The output is referred to the output reference (Ref) terminal which is normally grounded. This must be a low-impedance connection to ensure good common-mode rejection. A resistance of 8 in series with the Ref pin will cause a typical device to degrade to approximately 80dB CMR. Dual versions (INA2126) have feedback sense connections, SenseA and SenseB. These must be connected to their respective output terminals for proper operation. The sense connection can be used to sense the output voltage directly at the load for best accuracy. OFFSET TRIMMING The INA126 and INA2126 are laser trimmed for low offset voltage and offset voltage drift. Most applications require no external offset adjustment. Figure 2 shows an optional circuit for trimming the output offset voltage. The voltage applied to the Ref terminal is added to the output signal. An op amp buffer is used to provide low impedance at the Ref terminal to preserve good common-mode rejection. - VIN SETTING THE GAIN Gain is set by connecting an external resistor, RG, as shown: G = 5+ 80k RG RG INA126 + VIN VO V+ Ref 100A 1/2 REF200 (1) OPA237 10mV Adjustment Range Commonly used gains and RG resistor values are shown in Figure 1. The 80k term in equation 1 comes from the internal metal film resistors which are laser trimmed to accurate absolute values. The accuracy and temperature coefficient of these resistors are included in the gain accuracy and drift specifications. The stability and temperature drift of the external gain setting resistor, RG, also affects gain. RG's contribution to gain accuracy and drift can be directly inferred from the gain 100 10k 100 100A 1/2 REF200 Dual version has external sense connection. V- FIGURE 2.

FIGURE 1. Basic Connections. INA126, INA2126 SBOS062A www.ti.com 7 INPUT BIAS CURRENT RETURN The input impedance of the INA126/2126 is extremely high--approximately 109. However, a path must be provided for the input bias current of both inputs. This input bias current is typically -10nA (current flows out of the input terminals). High input impedance means that this input bias current changes very little with varying input voltage. Input circuitry must provide a path for this input bias current for proper operation. Figure 3 shows various provisions for an input bias current path. Without a bias current path, the inputs will float to a potential which exceeds the commonmode range and the input amplifiers will saturate. If the differential source resistance is low, the bias current return path can be connected to one input (see the thermocouple example in Figure 3). With higher source impedance, using two equal resistors provides a balanced input with advantages of lower input offset voltage due to bias current and better high-frequency common-mode rejection. Microphone, Hydrophone etc. INA126 47k LOW VOLTAGE OPERATION The INA126/2126 can be operated on power supplies as low as 1.35V. Performance remains excellent with power supplies ranging from 1.35V to 18V. Most parameters vary only slightly throughout this supply voltage range--see typical characteristic curves. Operation at very low supply voltage requires careful attention to ensure that the commonmode voltage remains within its linear range. See "Input Common-Mode Voltage Range." The INA126/2126 can be operated from a single power supply with careful attention to input common-mode range, output voltage swing of both op amps and the voltage applied to the Ref terminal. Figure 4 shows a bridge amplifier circuit operated from a single +5V power supply. The bridge provides an input common-mode voltage near 2.5V, with a relatively small differential voltage. INPUT PROTECTION The inputs are protected with internal diodes connected to the power supply rails. These diodes will clamp the applied signal to prevent it from exceeding the power supplies by more than approximately 0.7V. If the signal source voltage can exceed the power supplies, the source current should be limited to less than 10mA. This can generally be done with a series resistor. Some signal sources are inherently currentlimited and do not require limiting resistors. 47k Thermocouple The internal op amp A2 is identical to A1 and its output swing is limited to typically 0.7V from the supply rails. When the input common-mode range is exceeded (A2's output is saturated), A1 can still be in linear operation and respond to changes in the non-inverting input voltage. The output voltage, however, will be invalid. INA126 10k INA126 Center-tap provides bias current return. FIGURE 3. Providing an Input Common-Mode Current Path. INPUT COMMON-MODE RANGE The input common-mode range of the INA126/2126 is shown in the typical characteristic curves. The commonmode range is limited on the negative side by the output voltage swing of A2, an internal circuit node that cannot be measured on an external pin. The output voltage of A2 can be expressed as: - + - VO2 = 1.25 VIN - (VIN - VIN ) (10k/RG) CHANNEL CROSSTALK--DUAL VERSION The two channels of the INA2126 are completely independent, including all bias circuitry. At DC and low frequency there is virtually no signal coupling between channels. Crosstalk increases with frequency and is dependent on circuit gain, source impedance and signal characteristics. As source impedance increases, careful circuit layout will help achieve lowest channel crosstalk. Most crosstalk is produced by capacitive coupling of signals from one channel to the input section of the other channel. To minimize coupling, separate the input traces as far as practical from any signals associated with the opposite channel. A grounded guard trace surrounding the inputs helps reduce stray coupling between channels. Carefully balance the stray capacitance of each input to ground, and run the differential inputs of each channel parallel to each other, or directly adjacent on top and bottom side of a circuit board. Stray coupling then tends to produce a common-mode signal that is rejected by the IA's input.

A conversion rate of 10kS/s or slower assures enough current to turn on the reference diode. Converter input range is 1.2V. Output swing limitation of INA126 limits the A/D converter to somewhat greater than 11 bits of range. +5V 7 R1, C1, R2: 340Hz LP INA126 2.5V + V 6 A1 8 40k 8 R1 1k 2 10k Bridge Sensor INA126 and ADS7817 are available in fine-pitch MSOP-8 package 3 RG C1 0.47F 10k 3 1 -IN R2 1k A2 2.5V - V +IN 1 2 40k 5 1.2V ADS7817 12-Bit A/D VREF CS Ck 6 Serial Data 5 Chip Select 7 Clock 33A 4 6 8 4 D REF1004C-1.2 4 A similar instrumentation amplifier, INA125, provides an internal reference voltage for sensor excitation and/or A/D converter reference.

(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.
