SGM8634XS14

SGMICRO · Operational Amplifier · SOIC-14

SGM8634XS14 from SGMICRO, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	OUTA	output	Output of amplifier A, which provides rail-to-rail output swing into heavy loads.
2	-INA	input	Inverting input of amplifier A; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V.
3	+INA	input	Non-inverting input of amplifier A; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V.
4	+VS	power_in	Positive supply, operating from 2.5V to 5.5V (absolute maximum supply voltage is 6V); bypass with a 0.1µF ceramic capacitor close to the pin.
5	+INB	input	Non-inverting input of amplifier B; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V.
6	-INB	input	Inverting input of amplifier B; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V.
7	OUTB	output	Output of amplifier B, which provides rail-to-rail output swing into heavy loads.
8	OUTC	output	Output of amplifier C, which provides rail-to-rail output swing into heavy loads.
9	-INC	input	Inverting input of amplifier C; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V.
10	+INC	input	Non-inverting input of amplifier C; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V.
11	-VS	power_in	Negative supply; it is ground in single-supply operation, and for dual supplies (±1.25V to ±2.75V) it is bypassed to ground with its own 0.1µF capacitor.
12	+IND	input	Non-inverting input of amplifier D; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V.
13	-IND	input	Inverting input of amplifier D; the input common-mode voltage range includes ground and reaches -0.1V to +5.6V at VS = 5.5V.
14	OUTD	output	Output of amplifier D, which provides rail-to-rail output swing into heavy loads.
