# MCP6021T-E

**Microchip Tech** · Operational Amplifier · SOT-23-5

MCP6021T-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 | Op amp analog output, which is a low-impedance voltage source. |
| 2 | VSS | power_in | Negative power supply; typically connected to ground in single-supply operation. |
| 3 | VIN+ | power_in | Non-inverting 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, stated in the pin description as 2.5V to 6.0V above VSS, and it needs a bypass capacitor. |
