CS5464-IS

Overview

The CS5464-IS is an integrated power measurement device from Cirrus Logic, designed for high-performance energy metering applications. It combines three delta-sigma analog-to-digital converters, a power calculation engine, an energy-to-frequency converter, and a serial interface on a single chip. The component accurately measures instantaneous current and voltage to calculate VRMS, IRMS, instantaneous power, active power, apparent power, and reactive power. It features energy data linearity of ±0.1% of reading over a 1000:1 dynamic range and meets accuracy specifications for IEC, ANSI, and JIS standards.

Feature Summary

• Integrates three delta-sigma ADCs with a dedicated power calculation engine for comprehensive energy metrics.
• Includes an on-chip energy-to-pulse conversion capability and positive-only accumulation mode.
• Supports system calibrations, phase compensation, and temperature sensing within the device architecture.

Applications

• High-accuracy single-phase energy metering systems
• Power quality monitoring devices requiring RMS and power factor calculations
• Smart grid distribution units complying with IEC or ANSI standards

Procurement Notes

Verify the specific suffix designation carefully during procurement, as variations may indicate different temperature ranges or packaging options. Confirm availability status directly with authorized distributors, as lead times and stock levels fluctuate. Ensure that the ordering information matches the exact part number required for your design to avoid compatibility issues with existing firmware or hardware layouts.

Selection Notes

Select this component when precise multi-parameter power analysis is required in a compact form factor. Consider its integration of voltage sag detection and current fault detection if system protection features are needed. Evaluate the serial interface requirements against your microcontroller capabilities to ensure seamless communication without additional protocol converters.
