OPA1678IDRGR from Texas Instruments, in a WSON-8-EP(3x3). 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 | OUT A | output | Channel A output with rail-to-rail output swing capability. |
| 2 | -IN A | input | Inverting input for channel A. |
| 3 | +IN A | input | Noninverting input for channel A. |
| 4 | V- | power_in | Negative power supply (lowest potential); operating supply voltage range ±2.25V to ±18V (dual supply) or 4.5V to 36V (single supply). |
| 5 | +IN B | input | Noninverting input for channel B. |
| 6 | -IN B | input | Inverting input for channel B. |
| 7 | OUT B | output | Channel B output with rail-to-rail output swing capability. |
| 8 | V+ | power_in | Positive power supply (highest potential); operating supply voltage range ±2.25V to ±18V (dual supply) or 4.5V to 36V (single supply). |
| 9 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
