OPA855QDSGRQ1 from Texas Instruments, in a WSON-8-EP(2x2). 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 | FB | output | Feedback connection to output of amplifier |
| 2 | NC | unconnected | Do not connect |
| 3 | IN- | input | Inverting input |
| 4 | IN+ | input | Noninverting input |
| 5 | VS- | power_in | Negative voltage supply |
| 6 | OUT | output | Amplifier output |
| 7 | VS+ | power_in | Positive voltage supply |
| 8 | PD | input | Power down connection. PD = logic low = power off mode; PD = logic high = normal operation |
| 9 | Thermal pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
