MCP3201T-CI from Microchip Tech, in a SOIC-8. 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 | VREF | power_in | Reference voltage input that sets the analog input span (IN+ can vary from IN- to VREF + IN-). |
| 2 | IN+ | input | Positive analog input that can vary from IN- to VREF + IN-. |
| 3 | IN- | input | Negative analog input that can vary ±100 mV from VSS. |
| 4 | VSS | power_in | Ground. |
| 5 | CS/SHDN | input | Chip select/shutdown input; pulled low to initiate communication, pulled high to end a conversion and enter low-power standby, and must be high between conversions. |
| 6 | DOUT | output | SPI serial data output that shifts out the A/D conversion result, changing on the falling edge of each clock. |
| 7 | CLK | input | SPI serial clock input that initiates a conversion and clocks out each bit of the conversion result. |
| 8 | VDD | power_in | +2.7V to 5.5V power supply. |
