MCP3462-E/ST

Analog To Digital Converters (ADC) Overview

The MCP3462-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 3.2 µV RMS at 16x gain. It utilizes a 20 MHz SPI-compatible interface and includes advanced security features such as CRC checks and register map locking.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel architecture supporting differential or single-ended inputs
• 16-bit resolution with RMS effective resolution of 15.5 bits minimum
• Programmable Oversampling Ratio (OSR) from 32 to 98304
• Internal temperature sensor and burnout current sources for sensor detection

Analog To Digital Converters (ADC) Applications

• Precision sensor transducers including pressure, strain, flow, and force measurement
• Factory automation and process control systems
• Portable instrumentation requiring high accuracy
• Temperature measurement applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +125°C). Confirm the '/ST' designation corresponds to the 20-lead TSSOP package. Ensure the ordering code matches the dual-channel variant MCP3462 rather than the single-channel MCP3461 or quad-channel MCP3464.

Analog To Digital Converters (ADC) Selection Notes

Select this component when two independent ADC channels are required within a single package. Consider the internal sequencer (SCAN mode) if automatic multiplexing without MCU intervention is needed. Verify that the 2.7V to 3.6V AVDD range aligns with the system power rails, as DVDD can operate independently down to 1.8V.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MCP3461/2/4 family of 16-bit Delta-Sigma ADCs. The MCP3462 specifically provides two input channels, distinguishing it from the MCP3461 (single channel) and MCP3464 (quad channel). All variants share identical electrical characteristics, pinouts, and command sets, differing only in the number of available analog input channels.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers: MCP3461-E/ST (Single Channel), MCP3464-E/ST (Quad Channel). These parts are pin-compatible and functionally identical except for channel count.
