LF353MX 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	OUTA	output	Output of op-amp A. Drives ±13.5 V typical swing with VS=±15 V, RL=10 kΩ. Short-circuit protected (continuous).
2	IN-A	input	Inverting input of op-amp A. JFET input, input resistance ~10^12 Ω, bias current ~50 pA typical.
3	IN+A	input	Non-inverting input of op-amp A. JFET input, input common-mode range typically +15/−12 V at VS=±15 V.
4	V-	power_in	Negative supply rail (VEE). Operating range up to ±18 V absolute max; typical dual-supply operation at ±15 V.
5	IN+B	input	Non-inverting input of op-amp B. JFET input matching op-amp A.
6	IN-B	input	Inverting input of op-amp B. JFET input matching op-amp A.
7	OUTB	output	Output of op-amp B. Same drive characteristics as OUTA; ±13.5 V typical swing, short-circuit protected.
8	V+	power_in	Positive supply rail (VCC). Operating range up to ±18 V absolute max; supply current 3.6 mA typical (6.5 mA max).
