AD8671ARZ 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 pin configuration figure); it is not connected internally. |
| 2 | -IN | input | Inverting input; the absolute maximum differential input voltage is ±0.7 V. |
| 3 | +IN | input | Non-inverting input; the input voltage range is ±2.5 V with ±5 V supplies and ±12 V with ±15 V supplies. |
| 4 | V- | power_in | Negative supply; the part operates from dual supplies of ±5 V to ±15 V, with a 36 V absolute maximum supply voltage. |
| 5 | NC | unconnected | No connect pin (marked NC in the pin configuration figure); it is not connected internally. |
| 6 | OUT | output | Amplifier output; it sources or sinks up to ±10 mA at ±5 V supply and ±20 mA at ±15 V supply, and the output short-circuit duration is indefinite. |
| 7 | V+ | power_in | Positive supply; the part operates from dual supplies of ±5 V to ±15 V, with a 36 V absolute maximum supply voltage. |
| 8 | NC | unconnected | No connect pin (marked NC in the pin configuration figure); it is not connected internally. |
