OPA705UA 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; the pin is not connected to the amplifier circuit. |
| 2 | -In | input | Inverting input; the common-mode voltage range extends from (V-) - 0.3V to (V+) + 0.3V, and input signals more than 0.3V beyond the supply rails should be current-limited to 10mA or less. |
| 3 | +In | input | Non-inverting input; the common-mode voltage range extends from (V-) - 0.3V to (V+) + 0.3V, and input signals more than 0.3V beyond the supply rails should be current-limited to 10mA or less. |
| 4 | V- | power_in | Negative supply rail; the device is specified for dual supplies of ±2V to ±6V or single supply of 4V to 12V (V+ to V- total 13.2V absolute maximum). |
| 5 | NC | unconnected | No internal connection; the pin is not connected to the amplifier circuit. |
| 6 | Out | output | Amplifier output, which swings to within 40mV of the rail at light loads (>100kΩ) and is short-circuit protected to ground (continuous, one amplifier per package). |
| 7 | V+ | power_in | Positive supply rail; the device is specified for dual supplies of ±2V to ±6V or single supply of 4V to 12V (V+ to V- total 13.2V absolute maximum). |
| 8 | NC | unconnected | No internal connection; the pin is not connected to the amplifier circuit. |
