SGM8249-2XS8G

SGMICRO · Operational Amplifier · SOIC-8

SGM8249-2XS8G from SGMICRO, in a SOIC-8. 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 operation.
2 -INA input Inverting input of amplifier A; the input voltage range is -VS to (+VS) + 0.1V per the absolute maximum ratings.
3 +INA input Non-inverting input of amplifier A; the common-mode input voltage range is (-VS) to (+VS) - 1.5V.
4 -VS power_in Negative power supply; operation is 4.5V to 36V single supply or ±2.25V to ±18V dual supplies.
5 +INB input Non-inverting input of amplifier B; the common-mode input voltage range is (-VS) to (+VS) - 1.5V.
6 -INB input Inverting input of amplifier B; the input voltage range is -VS to (+VS) + 0.1V per the absolute maximum ratings.
7 OUTB output Output of amplifier B, which provides rail-to-rail output operation.
8 +VS power_in Positive power supply; the absolute maximum supply voltage is 40V.
