MCP33131-05T-E/MS

Analog To Digital Converters (ADC) Overview

The MCP33131-05T-E/MS is a 16-bit successive approximation register (SAR) analog-to-digital converter with a throughput rate of 500 kSPS. It features a single pseudo-differential input channel supporting a full-scale range from 0V to VREF. The device operates with an analog supply voltage (AVDD) of 1.8V and a digital I/O interface voltage (DVIO) ranging from 1.7V to 5.5V. An external reference voltage (VREF) between 2.5V and 5.1V is required. Typical current consumption is 1.4 mA during conversion and approximately 0.8 µA in standby mode. It utilizes an SPI-compatible serial interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging and the 'E' suffix denotes automotive grade qualification (AEC-Q100). Confirm the specific datasheet revision matches design requirements. Ensure AVDD, DVIO, and VREF power rails are properly decoupled as specified in the electrical characteristics table for optimal performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 500 kSPS throughput are required for single-ended signals. It is suitable for designs needing low power consumption and compatibility with 1.7V to 5.5V digital logic levels without level shifters. Consider the MSOP-10 package constraints and thermal resistance if operating at high ambient temperatures.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP331x1-XX family, which includes 12-bit, 14-bit, and 16-bit variants with 1 Msps or 500 kSPS speeds. The MCP33131 specifically provides the highest resolution in the series. Other members include MCP33121 and MCP33111 models with different resolutions and input types.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include MCP33131-10T-E/MS for higher speed (1 Msps) or MCP33131D-05T-E/MS for differential input configurations. Verify pinout compatibility and software register settings when substituting.
