MCP33141-10-E/MN

Analog To Digital Converters (ADC) Overview

The MCP33141-10-E/MN is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter from Microchip Technology. It operates at a throughput rate of 1 Msps with pseudodifferential input capability configured for single-ended signals. The device requires a fixed 1.8V analog supply (AVDD) and supports digital I/O voltages between 1.7V and 5.5V. It features an external reference voltage range from AVDD to 5.1V, SPI-compatible serial communication, and built-in self-calibration for offset, gain, and linearity errors. The component is AEC-Q100 qualified for automotive applications and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with no missing codes and 1 Msps throughput
• Ultra-low current consumption: ~1.5 µA in standby and ~0.66 mA during conversion
• Built-in data accumulator integrates up to 1024 samples to increase ENOB up to 18 bits
• ADC self-calibration for offset, gain, and linearity errors performed automatically at power-up or on-demand

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 the specific ordering suffix '-E/MN' corresponds to the TDFN-10 package variant as indicated by the model designation. Confirm that the required operating environment meets the AEC-Q100 Grade 1 qualification standards (-40°C to +125°C). Ensure the design accommodates the 1.8V analog supply requirement and the 1.7V to 5.5V digital interface range without external level shifters for compatible host devices.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input configuration is required alongside high-speed 1 Msps sampling. The wide digital I/O voltage range (1.7V–5.5V) simplifies interfacing with various microcontrollers like PIC32 families. Consider the internal data accumulator if higher effective resolution is needed for low-frequency signals, as it can average results to achieve up to 18 bits of ENOB.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP331x1-XX family, which includes 14-bit (MCP33151) and 12-bit (MCP33141) variants available in 1 Msps and 500 ksps speeds. The '10' suffix denotes the 1 Msps sample rate, while 'MN' specifies the TDFN-10 package. The family shares identical pinouts and functional characteristics, differing primarily in resolution and maximum throughput speed.

Analog To Digital Converters (ADC) Replacement Considerations

The MCP33151-10-E/MN serves as a higher-resolution alternative within the same package and family. For lower speed requirements, the MCP33141-05-E/MN offers 500 ksps operation. Ensure any substitute maintains the 1.8V AVDD requirement and single-ended input architecture.
