OPA656UB from Texas Instruments, 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 internal connection. |
| 2 | VIN- | power_in | Inverting input; common-mode input voltage range −4.3 V to +2.75 V; continuous input current ±10 mA maximum. |
| 3 | VIN+ | power_in | Noninverting input; common-mode input voltage range −4.3 V to +2.75 V; continuous input current ±10 mA maximum. |
| 4 | -VS | power_in | Negative power supply; absolute maximum ±6.5 V; recommended operating range ±5 V to ±6 V per supply. |
| 5 | NC | unconnected | No internal connection. |
| 6 | VOUT | output | Output of amplifier; voltage swing ±3.7 V to ±3.9 V with no load; output current sourcing 50 mA to 70 mA, sinking 50 mA to 70 mA. |
| 7 | +VS | power_in | Positive power supply; absolute maximum ±6.5 V; recommended operating range ±5 V to ±6 V per supply. |
| 8 | NC | unconnected | No internal connection. |
