AD8552 from Tokmas, 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 | Output of amplifier A, rail-to-rail output. |
| 2 | INA- | input | Inverting input of amplifier A, rail-to-rail input limited to Vss-0.5V to VDD+0.5V absolute maximum. |
| 3 | INA+ | input | Non-inverting input of amplifier A, rail-to-rail input limited to Vss-0.5V to VDD+0.5V absolute maximum. |
| 4 | VSS | power_in | Negative supply or ground; single-supply operation is specified from +1.8V to +5.5V between VDD and VSS. |
| 5 | INB+ | input | Non-inverting input of amplifier B, rail-to-rail input limited to Vss-0.5V to VDD+0.5V absolute maximum. |
