Texas Instruments · Operational Amplifier · SOIC-8
OPA704UA 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 | -In | input | Inverting input of the amplifier; input range extends 0.3V beyond the supply rails, with input current limited to 10mA if signals swing further. |
| 3 | +In | input | Non-inverting input of the amplifier; input range extends 0.3V beyond the supply rails, with input current limited to 10mA if signals swing further. |
| 4 | V- | power_in | Negative supply (ground in single-supply use); supply range V+ to V- is 4V to 12V specified, 13.2V absolute maximum. |
| 5 | NC | unconnected | No internal connection. |
| 6 | Out | output | Amplifier output with rail-to-rail swing to within 40mV of the rail, short-circuit current of ±40mA. |
| 7 | V+ | power_in | Positive supply; supply range V+ to V- is 4V to 12V specified, 13.2V absolute maximum. |
| 8 | NC | unconnected | No internal connection. |
