MCP6V91T-E from Microchip Tech, in a SOT-23-5. 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 | VOUT | output | Analog output pin, a low-impedance voltage source. |
| 2 | VSS | power_in | Negative power supply, connected to ground in single-supply use; VDD must be 2.4V to 5.5V above VSS. |
| 3 | VIN+ | power_in | Noninverting input, a high-impedance CMOS input with low bias current. |
| 4 | VIN- | power_in | Inverting input, a high-impedance CMOS input with low bias current. |
| 5 | VDD | power_in | Positive power supply, 2.4V to 5.5V above VSS, and needs bypass capacitors. |
