CS5484-INZ

Overview

The CS5484-INZ is a high-precision, three-phase energy management analog front-end (AFE) manufactured by Cirrus Logic. Designed for utility-grade metering applications, it integrates precision amplifiers and delta-sigma analog-to-digital converters to measure voltage, current, and power parameters across three phases. The device supports direct connection to low-side shunt resistors or external signal conditioning circuits. It features a serial peripheral interface (SPI) for digital communication and configuration. The component operates within a specified industrial temperature range and is housed in a compact surface-mount package suitable for dense PCB layouts.
