AD8629M

HGSEMI · Precision Op Amps · SOP-8

AD8629M from HGSEMI, in a SOP-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 Amplifier A output, rail-to-rail swing.
2 INA- input Amplifier A inverting input; common-mode range extends from VSS-0.1V to VDD+0.1V.
3 INA+ input Amplifier A non-inverting input; common-mode range extends from VSS-0.1V to VDD+0.1V.
4 VSS power_in Negative supply (ground in single-supply operation); for dual supplies bypass with 0.1µF ceramic capacitor.
5 INB+ input Amplifier B non-inverting input; common-mode range extends from VSS-0.1V to VDD+0.1V.
6 INB- input Amplifier B inverting input; common-mode range extends from VSS-0.1V to VDD+0.1V.
7 OUTB output Amplifier B output, rail-to-rail swing.
8 VDD power_in Positive supply, 1.8V to 5.5V single supply (absolute max 7.5V); place a 0.1µF ceramic capacitor close to the pin.
