OPA348AQDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No internal connection; the datasheet lists this pin as not connected (NC) in the 8-pin SOIC package.
2	-IN	input	Inverting input; for normal operation the input voltage must stay within (V-) - 0.2 V to (V+) + 0.2 V, and input current must be limited to 10 mA when the input exceeds the supply rails by more than 0.5 V.
3	+IN	input	Non-inverting input; for normal operation the input voltage must stay within (V-) - 0.2 V to (V+) + 0.2 V, and input current must be limited to 10 mA when the input exceeds the supply rails by more than 0.5 V.
4	V-	power_in	Negative (lowest) power supply; the device operates from 2.1 V to 5.5 V between V+ and V-.
5	NC	unconnected	No internal connection; the datasheet lists this pin as not connected (NC) in the 8-pin SOIC package.
6	OUT	output	Amplifier output; the output can be shorted to ground continuously (one amplifier per package), and the absolute maximum supply voltage is 7.5 V.
7	V+	power_in	Positive (highest) power supply; the device operates from 2.1 V to 5.5 V between V+ and V-, with an absolute maximum of 7.5 V.
8	NC	unconnected	No internal connection; the datasheet lists this pin as not connected (NC) in the 8-pin SOIC package.
