OPA2377AIDGKR from Texas Instruments, in a VSSOP-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	OUT A	output	Amplifier A output. Rail-to-rail CMOS output stage; short-circuit current +30/-50 mA, open-loop output impedance ~150 Ohm.
2	-IN A	input	Amplifier A inverting input. High-impedance CMOS input (IB = 0.2 pA typ); common-mode range (V-)-0.1V to (V+)+0.1V.
3	+IN A	input	Amplifier A non-inverting input. High-impedance CMOS input with EMI input filtering; input diode-clamped to supply rails (limit to <=10 mA if driven beyond rails).
4	V-	power_in	Negative supply rail (or ground for single-supply operation). Total supply Vs = (V+)-(V-) from 2.2V to 5.5V, absolute max 7V.
5	+IN B	input	Amplifier B non-inverting input. High-impedance CMOS input with EMI input filtering.
6	-IN B	input	Amplifier B inverting input. High-impedance CMOS input (IB = 0.2 pA typ).
7	V+	power_in	Positive supply rail. Total supply Vs = (V+)-(V-) from 2.2V to 5.5V, absolute max 7V; quiescent current 0.76 mA/ch typ.
8	OUT B	output	Amplifier B output. Rail-to-rail CMOS output stage; short-circuit current +30/-50 mA.
