**Microchip Tech** · Operational Amplifier · SC-70-5

MIC920YC5-TR 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 | IN+ | input | Noninverting input of the amplifier; keep trace capacitance low to avoid degrading performance. |
| 2 | V- | power_in | Negative supply; operating supply range is ±2.5V to ±9V (20V max total across V+ to V-). |
| 3 | IN- | input | Inverting input of the amplifier; keep trace capacitance low, and differential input voltage must not exceed 4V. |
| 4 | OUT | output | Amplifier output, stable driving any capacitive load, with short-circuit source current of 50mA min (±9V supplies). |
| 5 | V+ | power_in | Positive supply; operating supply range is ±2.5V to ±9V (20V max total across V+ to V-). |
