AD8551M5

HGSEMI · Precision Op Amps · SOT-23-5

AD8551M5 from HGSEMI, 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, typically within 5mV of the supply rail at loads above 100kΩ.
2 VSS power_in Negative supply (ground in single-supply operation); the supply range VDD to VSS is 1.8V to 5.5V, with an absolute maximum of 7.5V.
3 IN+ input Non-inverting input with rail-to-rail common-mode range from VSS-0.1V to VDD+0.1V and typical bias current of 20pA.
4 IN- input Inverting input with rail-to-rail common-mode range from VSS-0.1V to VDD+0.1V and typical bias current of 20pA.
5 VDD power_in Positive supply of +1.8V to +5.5V, which the datasheet says to bypass with a 0.1µF ceramic capacitor placed close to the pin.
