OPA132UA 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	NC	unconnected	No connect. Do not connect this pin. Existing layouts prior to revision C of the datasheet do not need to be redesigned (this pin was formerly an offset trim pin in older revisions).
2	-IN	input	Inverting input to the op-amp. FET (JFET) input with typical bias current of ±5pA (±50pA max at 25°C). Diode-clamped to supply rails; input signals swinging more than 0.5V beyond supplies must be current-limited to ≤10mA.
3	+IN	input	Noninverting input to the op-amp. FET (JFET) input with typical bias current of ±5pA. Common-mode range typically (V-)+2.5V to (V+)-3.5V. Diode-clamped to supply rails.
4	V-	power_in	Negative power supply. Operating range ±2.5V to ±18V (dual supply) or 9V to 36V (single supply, referenced to V+). Bypass with a low-ESR 10nF ceramic capacitor to ground placed close to the pin.
5	NC	unconnected	No connect. Do not connect this pin. Existing layouts prior to revision C of the datasheet do not need to be redesigned (this pin was formerly an offset trim pin in older revisions).
6	OUT	output	Op-amp output. Output can source up to 36mA and sink up to 30mA (short-circuit). Output swing typically within (V+)-1.1V and (V-)+0.9V with a 2kΩ load. Stable driving high capacitive loads with unity-gain stability.
7	V+	power_in	Positive power supply. Operating range ±2.5V to ±18V (dual supply) or 9V to 36V (single supply). Quiescent current ~4mA typical (4.8mA max) per amplifier. Bypass with a low-ESR 10nF ceramic capacitor to ground placed close to the pin.
8	NC	unconnected	No internal connection. Float this pin.
