MCP3918A1-E/SS

Overview

The MCP3918A1-E/SS is a single-channel analog front end (AFE) designed for energy metering applications. It features a 24-bit Sigma-Delta ADC with a sampling rate of 125 kS/s and supports I2C and SPI interfaces. Operating on a supply voltage between 2.7 V and 3.6 V, it provides a signal-to-noise ratio of 94 dB with a differential input type and a 1.2 V reference voltage. The component is housed in an SSOP-20 package and operates within a temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-resolution 24-bit Sigma-Delta analog-to-digital converter for precise energy measurement.
Supports dual digital communication protocols including I2C and SPI for flexible system integration.
Certified for automotive reliability under the AEC-Q100 standard.

Applications

Single-phase energy metering systems
Smart electricity meters
Utility billing infrastructure
