SGM8252AXS8G

SGMICRO · Operational Amplifier · SOIC-8

SGM8252AXS8G 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; the datasheet specifies rail-to-rail output swing (output voltage swing from rail: 25mV typ at VS=±2.5V, 140mV typ at VS=±18V).
2 -INA input Inverting input of amplifier A; the differential input voltage range is recommended to be within -0.7V to 0.7V, and the input common-mode range is (-VS)-0.05V to (+VS)-1.5V.
3 +INA input Non-inverting input of amplifier A; the input common-mode voltage range is (-VS)-0.05V to (+VS)-1.5V.
4 -VS power_in Negative power supply; for single-supply operation it is tied to ground (labelled -VS (GND) in the application figure), with a 0.1µF bypass capacitor recommended close to the pin.
5 +INB input Non-inverting input of amplifier B; the input common-mode range is (-VS)-0.05V to (+VS)-1.5V.
6 -INB input Inverting input of amplifier B; the differential input voltage range is recommended to be within -0.7V to 0.7V.
7 OUTB output Output of amplifier B; the datasheet specifies rail-to-rail output swing (output voltage swing from rail: 25mV typ at VS=±2.5V, 140mV typ at VS=±18V).
8 +VS power_in Positive power supply; the operating voltage range is 4.5V to 36V single supply (or ±2.25V to ±18V dual), with a 0.1µF ceramic bypass capacitor placed close to the pin.
