MCP3464T-E/NC

Analog To Digital Converters (ADC) Overview

The MCP3464T-E/NC is a quad-channel, 16-bit Delta-Sigma Analog-to-Digital Converter (ADC) manufactured by Microchip Technology. It supports 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 of 2.7V to 3.6V and a digital supply voltage 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 specific gain settings. It features a 20 MHz SPI-compatible interface and includes internal calibration registers for offset and gain error correction.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel architecture supporting differential or single-ended inputs
• Programmable data rate up to 153.6 ksps with Oversampling Ratios (OSR) from 32 to 98304
• Integrated internal sequencer (SCAN mode) for automatic multiplexing without MCU intervention
• Advanced security features including 16-bit CRC for SPI communications and register map locking

Analog To Digital Converters (ADC) Applications

• Precision sensor transducers and transmitters for pressure, strain, flow, and force measurement
• Factory automation and process control systems
• Portable instrumentation requiring high accuracy
• Temperature measurement applications utilizing the internal temperature sensor

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the required form factor, as the MCP3464 series is available in both 20-Lead UQFN (3 mm x 3 mm) and 20-Lead TSSOP packages. Confirm that the ordering suffix corresponds to the correct packaging method, such as tape and reel for surface mount assembly. Ensure the selected variant meets the extended temperature range specifications if operating conditions exceed standard industrial limits.

Analog To Digital Converters (ADC) Selection Notes

Select the MCP3464T-E/NC when four independent input channels are required within a single ADC solution. This model is suitable for designs needing high resolution (16-bit) and low noise performance, specifically where a SINAD of 97.2 dB is beneficial. Consider this part over the MCP3461 or MCP3462 if channel count is the primary constraint, while noting that the TSSOP package offers different thermal characteristics compared to the UQFN option.

Analog To Digital Converters (ADC) Part Context

The MCP3464T-E/NC belongs to the MCP3461/2/4 family of low-noise, 16-bit Delta-Sigma ADCs. This family shares common architectural features, including the SINC3 filter, digital gain capabilities, and the advanced security suite. The '4' in the part number specifically denotes the quad-channel configuration, distinguishing it from the single-channel MCP3461 and dual-channel MCP3462 variants which share similar electrical characteristics but differ in input multiplexer complexity.
