CS5460A-BSZR

Overview

The CS5460A-BSZR is a single-phase bidirectional power and energy monitoring integrated circuit manufactured by Cirrus Logic. It features a 24-bit resolution with a conversion rate of 4000 samples per second, housed in a 24-pin SSOP package measuring 8.5 x 5.6 x 1.88 mm. The device operates within a supply voltage range of 3.3 V to 5 V for digital logic and up to 5 V for analog circuits, supporting an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Integrates dual delta-sigma analog-to-digital converters for simultaneous sampling of voltage and current signals.
• Includes a high-speed energy calculation engine capable of computing active energy, instantaneous power, and RMS values.
• Supports self-boot mode to automatically initialize calibration data from external EEPROM memory.

Applications

• Single-phase electronic watt-hour meters
• Multi-user electricity metering systems
• Industrial field electrical quantity data acquisition
