OPA2170AIDR 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	OUT A	output	Output of amplifier channel A. Rail-to-rail output; short-circuit current typically ±17mA; open-loop output resistance ~900Ω at 1MHz.
2	-IN A	input	Inverting input of amplifier channel A. High-impedance CMOS input; input bias current typically ±8pA (±15pA max at 25°C). Absolute limit: (V−)−0.5V to (V+)+0.5V.
3	+IN A	input	Non-inverting input of amplifier channel A. Input common-mode range extends from (V−)−0.1V to (V+)−2V (extendable to V+ with reduced performance).
4	V-	power_in	Negative supply rail (or ground in single-supply operation). Total specified supply range V+ to V-: +2.7V to +36V (±1.35V to ±18V dual-supply).
5	+IN B	input	Non-inverting input of amplifier channel B. Same common-mode range as channel A.
6	-IN B	input	Inverting input of amplifier channel B. High-impedance CMOS input matching channel A characteristics.
7	OUT B	output	Output of amplifier channel B. Rail-to-rail output, matching channel A drive characteristics.
8	V+	power_in	Positive supply rail. Specified supply range +2.7V to +36V referenced to V-. Quiescent current typically 110µA per amplifier (145µA max).
