MCP3202-BI

Microchip Tech · Analog To Digital Converters (ADCs) · SOIC-8

MCP3202-BI 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 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.
2 CH0 input Channel 0 analog input, programmable as single-ended input or as IN+/IN- of the pseudo-differential pair.
3 CH1 input Channel 1 analog input, programmable as single-ended input or as IN+/IN- of the pseudo-differential pair.
4 VSS power_in Ground.
5 DIN input SPI serial data input used to clock in the input channel configuration data.
6 DOUT output SPI serial data output that shifts out the A/D conversion result, with data changing on the falling edge of each clock.
7 CLK input SPI serial clock that initiates a conversion and clocks out each bit of the conversion result.
8 VDD/VREF power_in +2.7V to 5.5V power supply and reference voltage input.
