MCP3462RT-E/ST

Analog To Digital Converters (ADC) Overview

The MCP3462RT-E/ST is a dual-channel, 16-bit Delta-Sigma Analog-to-Digital Converter (ADC) from Microchip Technology. It features programmable data rates up to 153.6 ksps and analog gains ranging from 0.33x to 64x. The device operates with an analog supply voltage (AVDD) of 2.7V to 3.6V and a digital supply voltage (DVDD) of 1.8V to 3.6V. Key performance metrics include a typical Signal-to-Noise and Distortion Ratio (SINAD) of 97.2 dB and a low noise floor of 2.3 µV RMS at specific settings. It integrates an internal 2.4V voltage reference, an internal temperature sensor, and burnout current sources for sensor diagnostics.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the marking on the package against the official datasheet specifications. Ensure the ordering suffix corresponds to the required tape and reel packaging format if automated assembly is planned. Confirm that the voltage levels on AVDD and DVDD pins remain within the specified operational ranges during system integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when two independent conversion channels are required. Compare the MCP3461R for single-channel needs or the MCP3464R for four-channel requirements. Consider the available packages: the 20-lead TSSOP for through-hole or standard surface mount, and the 20-lead UQFN for space-constrained designs. Verify that the maximum clock frequency supports the desired data rate.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MCP3461/2/4R family of Delta-Sigma ADCs. The '2' in the part number designates the dual-channel configuration, distinguishing it from the single-channel MCP3461R and the quad-channel MCP3464R. All variants share identical electrical characteristics, pinouts, and command sets, differing only in the number of available input channels.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include the MCP3461R-E/ST for single-channel applications and the MCP3464R-E/ST for four-channel applications. These parts maintain pin compatibility and software register compatibility.
