AD8551M 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 | NC | unconnected | No connect pin; not internally connected per the AD8551 SOP-8 pin diagram. |
| 2 | INA- | input | Inverting input of the amplifier; input common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 3 | INA+ | input | Non-inverting input of the amplifier; input common-mode range extends from VSS-0.1V to VDD+0.1V. |
| 4 | VSS | power_in | Negative supply, ground in single-supply operation; supply range VDD to VSS is 1.8V to 5.5V. |
| 5 | NC | unconnected | No connect pin; not internally connected per the AD8551 SOP-8 pin diagram. |
| 6 | OUT | output | Rail-to-rail amplifier output. |
| 7 | VDD | power_in | Positive supply, 1.8V to 5.5V single supply; bypass with a 0.1µF ceramic capacitor close to the pin. |
| 8 | NC | unconnected | No connect pin; not internally connected per the AD8551 SOP-8 pin diagram. |
