OPA725AIDR 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 (NC) on this pin, so it may be left unconnected. |
| 2 | -IN | input | Inverting input; the common-mode voltage range extends from V- to (V+) - 2V, and input signals swinging more than 0.5V 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- to (V+) - 2V, with CMRR excellent from V- to (V+) - 3V. |
| 4 | V- | power_in | Negative power supply; operation is specified from a single 4V to 12V supply or from ±2V to ±6V dual supplies. |
| 5 | NC | unconnected | No internal connection (NC) on this pin, so it may be left unconnected. |
| 6 | OUT | output | Rail-to-rail output that swings to within 150mV of the supply rails for light loads (>100kΩ) and within 250mV for 1kΩ loads. |
| 7 | V+ | power_in | Positive power supply; absolute maximum supply voltage is 13.2V. |
| 8 | NC | unconnected | No internal connection (NC) on this pin, so it may be left unconnected. |
