MCP33111D-05-E

Microchip Tech · Analog To Digital Converters (ADCs) · MSOP-10

MCP33111D-05-E from Microchip Tech, in a MSOP-10. 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 must be supplied within 2.5V to 5.1V and should be decoupled with a 10 µF tantalum capacitor.
2 AVDD power_in Analog supply input that requires 1.8V and should be decoupled with a 1 µF ceramic capacitor.
3 AIN+ input Differential positive analog input whose absolute maximum range is GND - 0.1V to VREF + 0.1V.
4 AIN- input Differential negative analog input whose absolute maximum range is GND - 0.1V to VREF + 0.1V.
5 GND power_in Common ground reference for both the analog supply (AVDD) and the digital I/O supply (DVIO).
6 CNVST input Active-low SPI chip-select and conversion-start digital input, where a new conversion starts on its rising edge.
7 SDO output SPI-compatible serial data output that shifts conversion data out MSB first on SCLK.
8 SCLK input SPI-compatible serial data clock input that synchronously shifts out the ADC output, rated up to 100 MHz.
9 SDI input SPI-compatible serial data input that must be tied to DVIO for normal operation.
10 DVIO power_in Digital input/output interface supply that operates from 1.7V to 5.5V and should be decoupled with a 0.1 µF ceramic capacitor.
