AD8651ARZ from Analog Devices, in a SOIC-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, marked NC in the datasheet pin configuration figure for the 8-Lead SOIC_N package. |
| 2 | -IN | input | Inverting input; the input common-mode voltage range is -0.1 V to +2.8 V at V+ = 2.7 V and -0.1 V to +5.1 V at V+ = 5 V. |
| 3 | +IN | input | Non-inverting input with rail-to-rail input stage, so the common-mode range extends to both supply rails. |
| 4 | V- | power_in | Negative supply rail, 0 V in the datasheet test conditions; absolute maximum supply voltage is 6.0 V and operation is specified from 2.7 V to 5.5 V single supply. |
| 5 | NC | unconnected | No connect pin, marked NC in the datasheet pin configuration figure for the 8-Lead SOIC_N package. |
| 6 | OUT | output | Amplifier output with rail-to-rail swing; the datasheet states 40 mA output current and 80 mA short-circuit limit for sourcing and sinking. |
| 7 | V+ | power_in | Positive supply rail; the amplifier runs from 2.7 V to 5.5 V single-supply, with an absolute maximum supply voltage of 6.0 V. |
| 8 | NC | unconnected | No connect pin, marked NC in the datasheet pin configuration figure for the 8-Lead SOIC_N package. |
