MCP33141-05T-E/MN

Analog To Digital Converters (ADC) Overview

The MCP33141-05T-E/MN is a single-channel, 12-bit Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Microchip Technology. It operates at a throughput rate of 500 ksps with no output latency. The device requires a 1.8V analog supply (AVDD) and a digital I/O voltage range of 1.7V to 5.5V (DVIO). It features an external reference input from AVDD to 5.1V, supporting a full-scale input range of 0V to VREF. Key electrical parameters include a typical Signal-to-Noise Ratio (SNR) of 73.3 dBFS, Integral Nonlinearity (INL) of ±0.09 LSB, and Differential Nonlinearity (DNL) of ±0.05 LSB. It utilizes a 3-wire SPI-compatible interface.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'T-E/MN' corresponds to the TDFN-10 package with tape-and-reel packaging as specified in the datasheet. Confirm that the component is AEC-Q100 qualified for automotive applications if required for the design. Ensure the host system supports the 1.7V to 5.5V digital I/O voltage range for proper interfacing without level shifters.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 12-bit resolution and 500 ksps throughput are sufficient for the application. It is suitable for designs requiring low power consumption and high accuracy with an external reference voltage. Consider the TDFN-10 package for thermal performance if operating in high-temperature environments up to +125°C. Ensure the analog input signal is within the 0V to VREF range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP33151/41-XX family of SAR ADCs. The '41' designation indicates 12-bit resolution, while '05' denotes the 500 ksps sample rate. The 'T' indicates tape-and-reel packaging, 'E' signifies RoHS compliance, and 'MN' identifies the TDFN-10 package type. This family shares features with the 14-bit MCP33151 variants but offers lower power consumption and cost.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. For pin-compatible alternatives within the same family, consider the MCP33141-10T-E/MN for higher speed (1 Msps) or the MCP33151-05T-E/MN for higher resolution (14-bit), ensuring voltage and interface compatibility.

Analog To Digital Converters (ADC) FAQ

What is the maximum SPI clock rate for the MCP33141-05?

The serial clock (SCLK) rate can go up to 100 MHz, although the recommended maximum is 30 MHz for optimal operation at the 500 ksps sample rate.

How does the built-in data accumulator function?

The accumulator can integrate up to 1024 consecutive converted samples. By automatically averaging these results, it increases the Effective Number of Bits (ENOB) up to 18 bits.

What is the input voltage range for the MCP33141-05?

The device supports a pseudodifferential input operation with a single-ended configuration. The input full-scale range is from 0V to the external reference voltage (VREF), which can be set from AVDD to 5.1V.
