CS5460CK-ISZ

Overview

The CS5460CK-ISZ is a single-phase, bi-directional power and energy metering integrated circuit manufactured by Cirrus Logic. It operates within a supply voltage range of 3.3V to 5V for digital logic and 0V to 5V for analog circuits. The device features a 24-bit resolution with a sampling rate of 4000 samples per second. It is housed in a 24-pin SSOP package measuring 8.5mm x 5.6mm x 1.88mm. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a programmable gain amplifier and dual delta-sigma analog-to-digital converters for precise signal acquisition.
• Includes internal digital filters and high-pass filters to process measurement data efficiently.
• Provides a dedicated energy calculation engine for accurate power monitoring.

Applications

• Residential electricity metering systems
• Single-phase bi-directional power monitoring
• Low-cost electronic energy meter solutions

Procurement Notes

Verify the specific suffix 'CK' against the manufacturer's current documentation to confirm pinout compatibility and electrical specifications. Ensure the design accommodates the 24-SSOP package dimensions and thermal requirements for the specified operating temperature range. Confirm that the 3.3V to 5V supply rails match the system architecture before procurement.

Selection Notes

Select this component for applications requiring high-resolution energy measurement in a compact form factor. The 24-bit resolution and 4000sps sampling rate support accurate billing-grade metering. Consider the SSOP package constraints and the need for external reference components if not internally integrated. Validate that the bi-directional capability aligns with the intended power flow direction.

Part Context

This part belongs to the Cirrus Logic CS5460 series of single-chip electronic metering solutions. These devices are designed to provide cost-effective and precise metering for residential applications. The series integrates analog front-end processing with digital filtering and energy calculation on a single CMOS chip, simplifying the design of next-generation electric meters.

Replacement Considerations

The CS5460A-BSZ is a related variant within the same family. Verify pin compatibility and specific electrical parameter differences before substitution. Check for any changes in package type or operational voltage ranges between the CK and BSZ suffixes.
