INA132UA 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 pin. Sets the output voltage reference level; typically tied to ground for bipolar supplies or to mid-supply for single-supply operation. Connects to the internal 40kΩ resistor of the feedback network. |
| 2 | -In | input | Inverting differential input. Connects through an internal 40kΩ resistor to the op amp inverting node. Differential input impedance is 80kΩ typical. |
| 3 | +In | input | Non-inverting differential input. Connects through an internal 40kΩ resistor to the op amp non-inverting node. Differential input impedance is 80kΩ typical. |
| 4 | V- | power_in | Negative supply rail. Connect to -1.35V to -18V for dual-supply operation or to ground (0V) for single-supply operation. Total supply (V+ to V-) must not exceed 36V. |
| 5 | Sense | input | Output sense pin. Normally tied to the Output pin (pin 6) directly; can be used to Kelvin-sense the load or drive a booster stage inside the feedback loop. Connects to the internal 40kΩ feedback resistor network. |
| 6 | Output | output | Amplifier output. Delivers (V+In − V−In) + VRef at unity gain. Output current limit is typically ±12mA continuous; stable driving capacitive loads up to 10,000pF. |
| 7 | V+ | power_in | Positive supply rail. Accepts 2.7V to 36V single-supply or +1.35V to +18V dual-supply. Total supply (V+ to V-) must not exceed 36V. |
| 8 | NC | unconnected | No Internal Connection. Leave floating or tie to any convenient potential; not electrically connected to the die. |
