AD8277ARZ-R7 from Analog Devices, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No connection; unused pin. |
| 2 | -INA | input | Inverting input for channel A; apply negative-side differential input signal. |
| 3 | +INA | input | Non-inverting input for channel A; apply positive-side differential input signal. |
| 4 | -VS | power_in | Negative power supply rail; connect to −2 V to −18 V. |
| 5 | +INB | input | Non-inverting input for channel B; apply positive-side differential input signal. |
| 6 | -INB | input | Inverting input for channel B; apply negative-side differential input signal. |
| 7 | NC | unconnected | No connection; unused pin. |
| 8 | REFB | input | Reference voltage input for channel B; sets output offset voltage level for channel B. |
| 9 | OUTB | output | Output for channel B; outputs amplified differential voltage with ±15 mA drive current capability. |
| 10 | SENSEB | output | Sense output for channel B; provides output voltage feedback node for remote load compensation. |
| 11 | +VS | power_in | Positive power supply rail; connect to +2 V to +36 V. |
| 12 | SENSEA | output | Sense output for channel A; provides output voltage feedback node for remote load compensation. |
| 13 | OUTA | output | Output for channel A; outputs amplified differential voltage with ±15 mA drive current capability. |
| 14 | REFA | input | Reference voltage input for channel A; sets output offset voltage level for channel A. |
