MCP3913A1-E/SS

Overview

The MCP3913A1-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) within a single package. The device supports a supply voltage of 3V and communicates via an SPI interface. It features a programmable data rate up to 125 ksps and includes CRC-16 checksum and register-map lock capabilities for robustness. The component is housed in a 28-pin SSOP package and meets AEC-Q100 automotive qualification standards.

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 security
• Supports programmable sampling rates up to 125 ksps to balance power consumption with advanced harmonic analysis

Applications

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

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with the target PCB footprint, as the SSOP variant differs from UQFN options. Confirm that the selected revision matches the required automotive or industrial grade specifications before finalizing procurement orders.

Selection Notes

Select this model when a compact 28-pin SSOP package is required for six-channel metering designs. Compare against the MCP3913A1-E/MV if a smaller UQFN form factor is preferred. Consider the MCP3914 family if eight channels are needed. Verify that the SPI interface timing requirements align with the host microcontroller capabilities.

Part Context

This component belongs to the MCP3913 series of analog front ends from Microchip Technology. The series is engineered for next-generation smart meters requiring industry-leading accuracy. It complements other Microchip data communication and power management solutions for complete metering subsystems.
