SGM8522XS

SGMICRO · Operational Amplifier · SOIC-8

SGM8522XS 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 swings rail-to-rail (typically 0.005V to 4.997V with a 500kΩ load to VS/2 at 5V) and is unity-gain stable for capacitive loads up to 250pF.
2 -INA input Inverting input of amplifier A; the input common mode range extends from (-VS) - 0.1V to (+VS) + 0.1V, with ESD diodes clamping the input to the supply rails.
3 +INA input Non-inverting input of amplifier A; the input common mode range extends from (-VS) - 0.1V to (+VS) + 0.1V, with ESD diodes clamping the input to the supply rails.
4 -VS power_in Negative supply rail, tied to GND in single-supply operation, and should be decoupled close to the pin with a 10μF ceramic capacitor in parallel with a 0.1μF or 0.01μF ceramic capacitor.
5 +INB input Non-inverting input of amplifier B; the input common mode range extends from (-VS) - 0.1V to (+VS) + 0.1V, with ESD diodes clamping the input to the supply rails.
6 -INB input Inverting input of amplifier B; the input common mode range extends from (-VS) - 0.1V to (+VS) + 0.1V, with ESD diodes clamping the input to the supply rails.
7 OUTB output Output of amplifier B, which swings rail-to-rail (typically 0.005V to 4.997V with a 500kΩ load to VS/2 at 5V) and is unity-gain stable for capacitive loads up to 250pF.
8 +VS power_in Positive supply rail, operating from 2.1V to 5.5V single supply with an absolute maximum of 6V from +VS to -VS, and should be decoupled close to the pin.
