SGM8249-1XN5G

SGMICRO · Operational Amplifier · SOT-23-5

SGM8249-1XN5G from SGMICRO, in a SOT-23-5. 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 OUT output Amplifier output with rail-to-rail output swing; the datasheet lists output short-circuit current limits of ±25mA typ at VS = ±2.25V and ±60mA typ at VS = ±18V.
2 -VS power_in Negative power supply; the device operates from 4.5V to 36V single supply or ±2.25V to ±18V dual supplies.
3 +IN input Non-inverting input; the common-mode input voltage range is (-VS) to (+VS) - 1.5V.
4 -IN input Inverting input of the amplifier; the common-mode input voltage range is (-VS) to (+VS) - 1.5V.
5 +VS power_in Positive power supply; the device operates from 4.5V to 36V single supply or ±2.25V to ±18V dual supplies.
