MCP3913A1T-E/SS

Overview

The MCP3913A1T-E/SS is a six-channel analog front end (AFE) designed for energy metering applications. It integrates six 24-bit delta-sigma analog-to-digital converters (ADCs). The device supports a 3V supply voltage and utilizes an SPI interface for communication. It features a programmable data rate of up to 125 ksps. The component meets AEC-Q100 automotive qualification standards and is housed in an SSOP-28 package.

Feature Summary

• Integrates six high-resolution 24-bit delta-sigma ADCs for simultaneous multi-phase signal acquisition
• Includes CRC-16 checksum and register-map lock mechanisms to enhance data integrity and system robustness
• Supports programmable sampling rates up to 125 ksps to enable advanced harmonic analysis and power optimization

Applications

• Three-phase smart electricity meters
• High-accuracy energy monitoring systems
• Industrial power quality analyzers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 'VAO' variant is not required if automotive reliability beyond standard AEC-Q100 is needed. Ensure the SSOP-28 footprint matches the target PCB design. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when six independent measurement channels are required within a single integrated circuit. It is suitable for designs prioritizing high dynamic range and low total harmonic distortion. Consider the 3V operating voltage constraint and SPI interface compatibility with the host microcontroller. Evaluate the need for automotive qualification versus commercial grade options based on the end-product environment.

Part Context

This part belongs to the MCP3913 family of analog front ends from Microchip Technology. It is positioned as a next-generation solution for energy metering, offering improved accuracy metrics compared to previous generations. The family includes variants with different channel counts and packaging options to support diverse metering architectures.

Replacement Considerations

The MCP3913A1-E/SS is the non-tape-and-reel equivalent. The MCP3914 series offers eight channels but may require software adaptation. Verify pin compatibility and register map differences before substituting with other AFE models.
