OPA333AID 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; can be left floating. |
| 2 | -IN | input | Inverting input terminal for signal input. |
| 3 | +IN | input | Noninverting input terminal; accepts common-mode voltage range (V-) - 0.1 to (V+) + 0.1 V. |
| 4 | V- | power_in | Negative (lowest) power supply terminal; operates with 1.8 V to 5.5 V supply range. |
| 5 | NC | unconnected | No internal connection; can be left floating. |
| 6 | OUT | output | Output terminal; provides rail-to-rail output within 50 mV of the supply rails. |
| 7 | V+ | power_in | Positive (highest) power supply terminal; operates with 1.8 V to 5.5 V supply range. |
| 8 | NC | unconnected | No internal connection; can be left floating. |
