GS8557-TR

Gainsil · Precision Op Amps · SOT-23-5

GS8557-TR from Gainsil, 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 swing (VOH 4.98V min 4.95V at Vs=5V, RL=10kΩ).
2 VSS power_in Negative supply or ground pin, bypassed with a 0.1µF ceramic capacitor in dual-supply operation.
3 IN+ input Non-inverting input with rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V) and absolute maximum of VSS-0.5V to VDD+0.5V.
4 IN- input Inverting input with rail-to-rail common-mode range (VSS-0.1V to VDD+0.1V) and absolute maximum of VSS-0.5V to VDD+0.5V.
5 VDD power_in Positive supply from 2.5V to 5.5V (absolute maximum 7.5V between VDD and VSS), with a 0.1µF ceramic bypass capacitor placed close to the pin.
