OPA374AIDR 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 internal connection. May be left floating.
2	-IN	input	Inverting (negative) input of the operational amplifier. Common-mode input voltage range extends 200 mV beyond each supply rail; input bias current is typically <1 pA (10 pA max).
3	+IN	input	Non-inverting (positive) input of the operational amplifier. Common-mode input voltage range extends 200 mV beyond each supply rail; input bias current is typically <1 pA (10 pA max).
4	V-	power_in	Negative (most negative) power supply. For single-supply operation tie to GND; for dual-supply operation tie to the negative rail. Total supply voltage (V+) − (V−) must be between 2.3 V and 5.5 V (2.7 V to 5.5 V recommended).
5	NC	unconnected	No internal connection. May be left floating.
6	OUT	output	Amplifier output. Rail-to-rail output stage swings within 25 mV of each supply rail; slew rate is 5 V/µs and short-circuit current is typically ±65 mA.
7	V+	power_in	Positive (most positive) power supply. Operating voltage range 2.3 V to 5.5 V referenced to V−; bypass to V− with a 0.1-µF ceramic capacitor placed close to the pin.
8	NC	unconnected	No internal connection. May be left floating.
