INA2132UA from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection. Leave floating or tie to a convenient potential. |
| 2 | -In A | input | Inverting differential input of channel A. Connects through an internal 40kΩ laser-trimmed resistor to the op-amp summing junction. Common-mode range extends to the negative supply. |
| 3 | +In A | input | Non-inverting differential input of channel A. Connects through an internal 40kΩ laser-trimmed resistor to the op-amp non-inverting node. |
| 4 | V- | power_in | Negative power supply. Connect to ground for single-supply operation or to the negative rail (down to -18V) for dual-supply operation. Total supply (V+ to V-) must not exceed 36V. |
| 5 | +In B | input | Non-inverting differential input of channel B. Connects through an internal 40kΩ laser-trimmed resistor to the op-amp non-inverting node. |
| 6 | -In B | input | Inverting differential input of channel B. Connects through an internal 40kΩ laser-trimmed resistor to the op-amp summing junction. |
| 7 | NC | unconnected | No internal connection. Leave floating or tie to a convenient potential. |
| 8 | Ref B | input | Reference pin for channel B. Sets the output reference level; typically tied to ground for dual-supply or to mid-supply (Vs/2) for single-supply operation. Connected via internal 40kΩ resistor to the feedback network. |
| 9 | Out B | output | Difference amplifier output for channel B. Unity-gain output of (+In B - -In B) + Ref B. Short-circuit current typically ±12mA; stable driving up to 10nF. |
| 10 | Sense B | input | Sense (feedback) pin for channel B. Typically tied directly to Out B for unity gain; can be used for remote-sense connections or to configure alternate gains with external resistors. |
| 11 | V+ | power_in | Positive power supply. Single supply 2.7V to 36V, or dual supply +1.35V to +18V. Bypass locally with a 0.1µF ceramic capacitor to V-. |
| 12 | Sense A | input | Sense (feedback) pin for channel A. Typically tied directly to Out A for unity gain; can be used for remote-sense connections or to configure alternate gains with external resistors. |
| 13 | Out A | output | Difference amplifier output for channel A. Unity-gain output of (+In A - -In A) + Ref A. Short-circuit current typically ±12mA; stable driving up to 10nF. |
| 14 | Ref A | input | Reference pin for channel A. Sets the output reference level; typically tied to ground for dual-supply or to mid-supply (Vs/2) for single-supply operation. Connected via internal 40kΩ resistor to the feedback network. |
