OPA333AIDR from UMW, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection; can be left floating. |
| 2 | -IN | input | Inverting input; common-mode voltage range (V−) − 0.1 V to (V+) + 0.1 V. |
| 3 | +IN | input | Noninverting input; common-mode voltage range (V−) − 0.1 V to (V+) + 0.1 V. |
| 4 | V- | power_in | Negative (lowest) power supply; supply voltage range 1.8 V to 5.5 V. |
| 5 | NC | unconnected | No internal connection; can be left floating. |
| 6 | OUT | output | Output; rail-to-rail output swing within 50 mV of rails at RL = 10 kΩ. |
| 7 | V+ | power_in | Positive (highest) power supply; supply voltage range 1.8 V to 5.5 V. |
| 8 | NC | unconnected | No internal connection; can be left floating. |
