MCP6V91UT-E from Microchip Tech, in a SC-70-5. 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 | VIN+ | power_in | Noninverting input; a high-impedance CMOS input with low bias currents, and for normal operation it must stay between VSS and VDD. |
| 2 | VSS | power_in | Negative power supply; connect to ground in single-supply use, with VDD 2.4 V to 5.5 V above it. |
| 3 | VIN- | power_in | Inverting input; a high-impedance CMOS input with low bias currents, and for normal operation it must stay between VSS and VDD. |
| 4 | VOUT | output | Analog output; a low-impedance voltage source. |
| 5 | VDD | power_in | Positive power supply, 2.4 V to 5.5 V higher than VSS; it requires bypass capacitors. |
