INA132U from Texas Instruments, in a SOIC-8. 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 | Ref | input | Reference input. Drive with a low-impedance source; sets the output reference (zero) voltage. Swapping pins 1 and 3 will degrade CMR. |
| 2 | -In | input | Negative (inverting) input of the difference amplifier. Internally tied to the op amp inverting input through a 40kΩ resistor. |
| 3 | +In | input | Positive (non-inverting) input of the difference amplifier. Internally tied to the op amp non-inverting input through a 40kΩ resistor. |
| 4 | V- | power_in | Negative supply rail. Connect to ground for single-supply operation (2.7V to 36V) or to a negative rail for dual-supply operation (±1.35V to ±18V). |
| 5 | Sense | input | Sense input. Drive with a low-impedance source; typically tied to Output for standard difference-amp operation, or to a remote load node for Kelvin sensing. Swapping pins 2 and 5 will degrade CMR. |
| 6 | Output | output | Amplifier output. Unity-gain difference of (+In) - (-In) referenced to the Ref pin. Rail-to-rail swing within ~1V of V+ and 0.5V of V- with a 100kΩ load. |
| 7 | V+ | power_in | Positive supply rail. Accepts 2.7V to 36V single-supply or +1.35V to +18V dual-supply. |
| 8 | NC | unconnected | No internal connection. Leave floating (datasheet says 保持未连接 / keep unconnected). |
