MCP33131-05T-E/MN

Analog To Digital Converters (ADC) Overview

The MCP33131-05T-E/MN is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter with a throughput rate of 500 kSPS. It 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. The device features pseudo-differential input operation with a full-scale range of 0V to VREF, where the external reference voltage ranges from 2.5V to 5.1V. Typical power consumption during conversion is 4.2 mW at 500 kSPS, dropping to approximately 0.8 µA in standby mode. It supports SPI-compatible serial communication with clock rates up to 100 MHz.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with no missing codes and 500 kSPS sampling rate
• Ultra-low current consumption: ~1.4 mA during conversion and ~0.8 µA in standby
• Wide digital I/O voltage range (1.7V to 5.5V) for direct interfacing without level shifters
• Internal self-calibration for offset, gain, and linearity errors

Analog To Digital Converters (ADC) Applications

• High-Precision Data Acquisition
• Medical Instruments
• Test Equipment
• Electric Vehicle Battery Management Systems
• Motor Control Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'T' indicates tape-and-reel packaging and '/MN' specifies the TDFN-10 package. Confirm the '-E' suffix denotes the extended industrial temperature grade (-40°C to +125°C). Ensure the specific revision of the datasheet DS20006122A matches the component batch for accurate electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 16-bit resolution and 500 kSPS throughput are required. The TDFN-10 package is suitable for space-constrained designs. Ensure the host system can provide a stable 1.8V analog supply and a DVIO within the 1.7V to 5.5V range. Verify that the application requires pseudo-differential or single-ended inputs compatible with the 0V to VREF range.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MCP331x1-XX family of SAR ADCs, which also includes 14-bit (MCP33121) and 12-bit (MCP33111) variants. The '-05' designation distinguishes it from the '-10' variant by reducing the maximum sample rate from 1 Msps to 500 kSPS while maintaining the same 16-bit resolution and low-power characteristics.
