MCP3913A1-E/MV

Overview

The MCP3913A1-E/MV 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) with a 3V operating supply voltage and SPI serial interface. The device utilizes an SSOP-28 package and supports surface mount installation. It features programmable data rates up to 125 ksps, CRC-16 checksums, and register-map lock capabilities for robust signal acquisition in high-accuracy power monitoring systems.

Feature Summary

• Integrates six 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 data rates up to 125 ksps to balance power consumption and advanced signal analysis requirements

Applications

• Three-phase smart electricity meters
• High-accuracy energy measurement systems
• Advanced signal analysis for harmonic content calculation

Procurement Notes

Verify the specific package variant, as the MV suffix typically denotes UQFN-40 while other variants use SSOP-28. Confirm AEC-Q100 automotive qualification status if required for your application. Ensure compatibility with the 3V supply voltage and SPI interface timing specifications before integration into the design.

Selection Notes

Select this component when six independent channels of high-resolution energy measurement are required within a single integrated circuit. Consider the trade-off between the higher data rate capability for harmonic analysis and the low-power modes available for extended battery life or reduced thermal output in dense metering environments.

Part Context

This part belongs to the MCP3913 family of analog front ends from Microchip Technology. It is positioned alongside the eight-channel MCP3914 variant, offering a cost-effective solution for applications requiring fewer than eight measurement channels while maintaining industry-leading accuracy metrics such as high SINAD and SFDR values.
