OPA2830IDR 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	VOUT1	output	Output, channel 1. Rail-to-rail-ish output stage with typical swing to within 25mV of supplies; +/-75mA drive capability.
2	VIN1-	input	Negative (inverting) input signal, channel 1. Differential input impedance 10kOhm
3	VIN1+	input	Positive (noninverting) input signal, channel 1. Input voltage range extends from below Vs- up to within 1.8V of Vs+.
4	VS-	power_in	Negative (lowest) power supply. Connect to ground for single-supply operation, or to negative rail for dual-supply operation. Total supply Vs+ - Vs- from 3V to 11V (max +/-6.5V absolute).
5	VIN2+	input	Positive (noninverting) input signal, channel 2. Same input range and impedance as channel 1.
6	VIN2-	input	Negative (inverting) input signal, channel 2. Same input impedance as channel 1.
7	VOUT2	output	Output, channel 2. Same drive capability as channel 1.
8	VS+	power_in	Positive (highest) power supply. Quiescent current 8.8mA typ at Vs=5V. Bypass with 0.1uF to VS- close to the pin.
