MCP3564RT-E/NC

Analog To Digital Converters (ADC) Overview

The MCP3564RT-E/NC is a quad-channel, 24-bit Delta-Sigma Analog-to-Digital Converter (ADC) manufactured by Microchip Technology. It features programmable data rates up to 153.6 ksps and gains ranging from 0.33x to 64x. The device integrates an internal 2.4V voltage reference with low temperature drift, an internal oscillator, and a temperature sensor. Key performance metrics include 106.7 dB SINAD, -116 dBc THD, and 120 dBc SFDR at 4800 SPS with unity gain. It operates on analog supplies of 2.7V to 3.6V and digital supplies of 1.8V to 3.6V, supporting an extended temperature range from -40°C to +125°C in a 20-lead UQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates the inclusion of the 20-lead TSSOP package option alongside the standard UQFN, as defined in the MCP3561/2/4R datasheet series. Confirm that the 'E' suffix denotes the extended industrial temperature range (-40°C to +125°C). Ensure the 'NC' designation aligns with the manufacturer's lead-free and halogen-free compliance standards. Cross-reference the exact part number against the official Microchip database to confirm current production status and availability.

Analog To Digital Converters (ADC) Selection Notes

Select the MCP3564RT-E/NC when four independent high-resolution channels are required within a compact footprint. This model is suitable for designs needing dynamic reconfiguration of oversampling ratios and gain settings without MCU intervention via the internal sequencer. Consider this component for applications demanding advanced data integrity through CRC checks and secure register access. It is appropriate for battery-powered devices due to its ultra-low shutdown current capabilities.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MCP3561/2/4R family of 24-bit Delta-Sigma ADCs. The '4' in the model number specifies the quad-channel variant, distinguishing it from the single-channel MCP3561R and dual-channel MCP3562R. The 'R' suffix differentiates this series from the non-R variants by offering additional package options, specifically the 20-lead TSSOP. All members share identical core electrical characteristics and pinouts where applicable.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include MCP3561RT-E/NC for single-channel needs and MCP3562RT-E/NC for dual-channel requirements. For non-R series equivalents, consider MCP3564T-E/NC, noting potential differences in available package types. Verify pin compatibility and software register map alignment before substituting.
