LM6172IMX 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	OUTPUT A	output	Output of amplifier A. Drives up to 50mA continuous output current; output swings to within ~1.8V of the supply rails with a 1kOhm load at +/-15V.
2	INVERTING INPUT A	input	Inverting (-) input of amplifier A. Voltage feedback topology; typical input bias current 1.2uA, input offset current 0.02uA.
3	NON-INVERTING INPUT A	input	Non-inverting (+) input of amplifier A. Common-mode input range typically +/-13.5V on +/-15V supplies; differential input voltage limited to +/-10V.
4	V-	power_in	Negative supply rail. Total supply voltage (V+ - V-) must be within 5.5V to 36V (absolute max 36V). Typically -15V or -5V.
5	NON-INVERTING INPUT B	input	Non-inverting (+) input of amplifier B. Common-mode input range typically +/-13.5V on +/-15V supplies; differential input voltage limited to +/-10V.
6	INVERTING INPUT B	input	Inverting (-) input of amplifier B. Voltage feedback topology; typical input bias current 1.2uA, input offset current 0.02uA.
7	OUTPUT B	output	Output of amplifier B. Drives up to 50mA continuous output current; output swings to within ~1.8V of the supply rails with a 1kOhm load at +/-15V.
8	V+	power_in	Positive supply rail. Total supply voltage (V+ - V-) must be within 5.5V to 36V (absolute max 36V). Typically +15V or +5V. Total supply current 4.6mA typical for both amplifiers.
