NCV2904DR2G from onsemi, 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	OUTA	output	Output of amplifier A. Push-pull output stage; internally short-circuit protected (Isc ≈ 40 mA typ). Output swings from VEE+VOL (~5-20 mV above VEE with RL=10 kΩ) up to VCC−1.5 V.
2	INA-	input	Inverting input of amplifier A. Low input bias current (typ −45 nA); differential input voltage range up to ±VCC. Common-mode range extends to VEE (ground).
3	INA+	input	Non-inverting input of amplifier A. Low input bias current (typ −45 nA); common-mode input voltage range from 0 V (VEE) up to VCC−1.7 V. ESD-clamped input.
4	VEE/GND	power_in	Negative supply / ground return for both amplifiers. Tie to 0 V in single-supply operation (3.0 V ≤ VCC ≤ 32 V) or to a negative rail (down to −16 V) in split-supply operation.
5	INB+	input	Non-inverting input of amplifier B. Low input bias current (typ −45 nA); common-mode input voltage range from 0 V (VEE) up to VCC−1.7 V. ESD-clamped input.
6	INB-	input	Inverting input of amplifier B. Low input bias current (typ −45 nA); differential input voltage range up to ±VCC. Common-mode range extends to VEE (ground).
7	OUTB	output	Output of amplifier B. Push-pull output stage; internally short-circuit protected (Isc ≈ 40 mA typ). Output swings from VEE+VOL (~5-20 mV above VEE with RL=10 kΩ) up to VCC−1.5 V.
8	VCC	power_in	Positive supply pin, common to both amplifiers. Single-supply range 3.0 V to 32 V, or +1.5 V to +16 V in split-supply mode. Total quiescent current typ 0.7 mA at VCC=5 V.
