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.
