OPA340UA 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 | Negative (inverting) input of the op-amp. Rail-to-rail input; common-mode range extends 500 mV below V- and 500 mV above V+. |
| 3 | +IN | input | Positive (noninverting) input of the op-amp. Rail-to-rail input; common-mode range extends 500 mV below V- and 500 mV above V+. |
| 4 | V- | power_in | Negative (lowest) power supply. Typically GND in single-supply configurations. Total supply range V+ to V- is 2.5 V to 5.5 V. |
| 5 | NC | unconnected | No internal connection. Can be left floating. |
| 6 | OUT | output | Op-amp output. Rail-to-rail output swings to within 1 mV of V+/V- with a 100-kΩ load. |
| 7 | V+ | power_in | Positive (highest) power supply. Single-supply operation from 2.5 V to 5.5 V (dual-supply ±1.25 V to ±2.75 V). |
| 8 | NC | unconnected | No internal connection. Can be left floating. |
