MCP33131D-05-E/MN

Analog To Digital Converters (ADC) Overview

The MCP33131D-05-E/MN is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Microchip Technology. It operates at a throughput rate of 500 kSPS with differential input capability and no output latency. The device requires a fixed 1.8V analog supply (AVDD) and supports a digital I/O voltage range of 1.7V to 5.5V (DVIO). It utilizes an external reference voltage between 2.5V and 5.1V. Key electrical specifications include a typical SNR of 91.3 dBFS, ±2 LSB INL, and ±0.8 LSB DNL. It features AEC-Q100 qualification for Grade 1 (-40°C to +125°C) and is housed in a TDFN-10 package.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 500 kSPS sampling rate and differential input architecture
• Ultra-low power consumption: ~1.4 mA during conversion and ~0.8 µA in standby mode
• Wide digital interface compatibility with DVIO ranging from 1.7V to 5.5V
• Integrated self-calibration for offset, gain, and linearity errors

Analog To Digital Converters (ADC) Applications

• High-precision data acquisition systems
• Medical instruments and diagnostic equipment
• Electric vehicle battery management systems
• Motor control applications
• Switch-mode power supply monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure that the external reference voltage requirements and decoupling capacitor recommendations are strictly followed during design implementation to maintain specified performance levels.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution ADC with low power consumption is required. The 500 kSPS throughput suits applications where 1 Msps is unnecessary. Ensure the host microcontroller supports SPI communication and can provide the necessary CNVST trigger signals for operation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP331x1D-XX family of SAR ADCs, which also includes 12-bit and 14-bit variants (MCP33111D, MCP33121D) and higher-speed 1 Msps versions (MCP33131D-10). The '05' suffix indicates the 500 kSPS speed grade, while 'MN' denotes the TDFN-10 package option.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include MCP33131D-10-E/MN (1 Msps version) or lower-resolution variants like MCP33121D-05-E/MN. Cross-vendor replacements require careful evaluation of pinout compatibility, SPI timing, and power supply constraints.
