OPA855IDSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | FB | input | Feedback input pin; connect to feedback network for transimpedance amplifier or gain-of-voltage configurations. |
| 2 | NC | unconnected | No connect pin; provides isolation between FB and IN- pins to minimize parasitic capacitance coupling. |
| 3 | IN- | input | Inverting input pin; common-mode input voltage range 1.1V to 4.6V at 5V supply with CMRR >80dB. |
| 4 | IN+ | input | Non-inverting input pin; common-mode input voltage range 1.1V to 4.6V at 5V supply with CMRR >80dB. |
| 5 | VS- | power_in | Negative power supply pin; connect to ground in single-supply or negative rail in split-supply configuration. |
| 6 | OUT | output | Amplifier output pin; maximum output swing 3VPP with output current capability up to 65-80mA. |
| 7 | VS+ | power_in | Positive power supply pin; operating voltage range 3.3V to 5.25V with 17.8mA typical quiescent current at 5V. |
| 8 | PD | input | Power-down control pin; logic low voltage (≤0.65V) disables amplifier for low-power operation, logic high (≥1.8V) enables normal operation. |
| 9 | Thermal Pad | power_in | Exposed thermal pad; must be soldered to printed circuit board and connected to VS- for thermal management and mechanical stability. |
