MCP33131D-05T-E/MN

Analog To Digital Converters (ADC) Overview

The MCP33131D-05T-E/MN is a 16-bit, single-channel successive approximation register (SAR) analog-to-digital converter with a throughput rate of 500 kSPS. It operates with a 1.8V analog supply (AVDD) and a 1.7V to 5.5V digital I/O supply (DVIO). The device features differential inputs with a full-scale range of -VREF to +VREF, supported by an external reference voltage between 2.5V and 5.1V. Typical current consumption is 1.4 mA during conversion and approximately 0.8 µA in standby mode. It includes internal self-calibration for offset, gain, and linearity errors, ensuring no missing codes across its resolution.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'T' indicates tape-and-reel packaging and 'E' denotes extended temperature grade (-40°C to +125°C). Confirm the package type 'MN' corresponds to the TDFN-10 option. Ensure the specific revision DS20005947B matches the required documentation version for design-in validation.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 16-bit accuracy is required at speeds up to 500 kSPS. The DVIO range allows direct interfacing with 3.3V or 5V logic without level shifters. For higher speeds, consider the MCP33131D-10 variant. Ensure the application can provide a stable VREF between 2.5V and 5.1V, as performance metrics like SNR are dependent on this reference voltage.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MCP331x1D family of SAR ADCs, which also includes 14-bit (MCP33121D) and 12-bit (MCP33111D) variants. The family shares identical pinouts, interfaces, and power characteristics, differing primarily in resolution and maximum sample rates (1 Msps vs. 500 kSPS). The 'D' suffix indicates the automotive-grade AEC-Q100 qualification.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include MCP33131D-10T-E/MN (higher speed, same resolution) or MCP33121D-05T-E/MN (lower resolution, same speed). Cross-family replacements require verification of pin compatibility and interface timing.
