OPA703UA 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 connection; the datasheet gives no function or electrical limit for this pin. |
| 2 | -In | input | Inverting input; signals that swing more than 0.3 V beyond the supply rails should be current-limited to 10 mA or less, and the common-mode range is (V-) - 0.3 V to (V+) + 0.3 V. |
| 3 | +In | input | Non-inverting input with the same common-mode range of (V-) - 0.3 V to (V+) + 0.3 V and the same 10 mA input-current limit for signals beyond the rails. |
| 4 | V- | power_in | Negative supply rail; the part is specified for single supply 4 V to 12 V or dual supplies ±2 V to ±6 V, and the absolute maximum total supply V+ to V- is 13.2 V. |
| 5 | NC | unconnected | No connection; the datasheet gives no function or electrical limit for this pin. |
| 6 | Out | output | Amplifier output that swings to within 40 mV of the rail at RL = 100 kΩ, with output current of ±10 mA and short-circuit current of ±40 mA (continuous short-circuit to ground permitted, one amplifier per package). |
| 7 | V+ | power_in | Positive supply rail; the part is specified for single supply 4 V to 12 V or dual supplies ±2 V to ±6 V, and the absolute maximum total supply V+ to V- is 13.2 V. |
| 8 | NC | unconnected | No connection; the datasheet gives no function or electrical limit for this pin. |
