**Microchip Tech** · Programmable/Variable Gain Amplifiers (PGAs/VGAs) · SOIC-14

MCP6S26-I from Microchip Tech, in a SOIC-14. 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 | Low-impedance analog output whose value is set by the selected gain, the selected input and the voltage at VREF. |
| 2 | CH0 | input | High-impedance CMOS analog input with low bias current; the internal MUX selects which input is amplified to the output. |
| 3 | CH1 | input | High-impedance CMOS analog input with low bias current; the internal MUX selects which input is amplified to the output. |
| 4 | CH2 | input | High-impedance CMOS analog input with low bias current; the internal MUX selects which input is amplified to the output. |
| 5 | CH3 | input | High-impedance CMOS analog input with low bias current; the internal MUX selects which input is amplified to the output. |
| 6 | CH4 | input | High-impedance CMOS analog input with low bias current; the internal MUX selects which input is amplified to the output. |
| 7 | CH5 | input | High-impedance CMOS analog input with low bias current; the internal MUX selects which input is amplified to the output. |
| 8 | VREF | power_in | External reference pin that should be held between VSS and VDD; its voltage shifts the output voltage. |
| 9 | VSS | power_in | Negative power supply; connected to ground in typical single-supply configuration. |
| 10 | CS | input | SPI chip select input; a Schmitt-triggered CMOS logic input. |
| 11 | SI | input | SPI serial data input; a Schmitt-triggered CMOS logic input. |
| 12 | SO | output | SPI serial data output; a CMOS push-pull output that never goes High-Z and is forced low once the device is deselected. |
| 13 | SCK | input | SPI clock input; a Schmitt-triggered CMOS logic input. |
| 14 | VDD | power_in | Positive power supply, 2.5V to 5.5V above VSS; requires a 0.1 µF local bypass capacitor at the pin. |
