MCP33151D-05-E/MS

Analog To Digital Converters (ADC) Overview

The MCP33151D-05-E/MS is a single-channel, 14-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 an external reference voltage range from AVDD to 5.1 V. The device utilizes a 1.8 V analog supply and a 1.7 V to 5.5 V digital I/O interface, supporting SPI-compatible communication up to 100 MHz. Key electrical specifications include a typical signal-to-noise ratio of 83.7 dBFS, integral nonlinearity of ±0.27 LSB, and differential nonlinearity of ±0.11 LSB. It features built-in self-calibration for offset, gain, and linearity errors, along with a data accumulator that can increase effective resolution up to 18.5 bits.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'E/MS' corresponds to the MSOP-10 package and commercial/automotive grade availability. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the external reference voltage requirements align with system design constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution ADC with low latency is required. The 500 kSPS throughput suits applications where moderate speed is sufficient. Verify compatibility with host microcontrollers using the wide DVIO range (1.7V–5.5V). Consider the internal data accumulator if higher effective resolution is needed without increasing sample rates.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP331x1D-XX family of SAR ADCs, which also includes 1 Msps variants (MCP33151D-10) and 12-bit versions (MCP33141D-XX). All members share similar pinouts and interfaces but differ in resolution and throughput. The 'D' suffix indicates the device variant, while '05' specifies the 500 kSPS speed grade.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include MCP33151D-10-E/MS (higher speed) and MCP33141D-05-E/MS (lower resolution). Cross-family replacements require verification of pin compatibility, voltage levels, and performance metrics against original design specifications.
