CS5490-ISZR

Overview

The CS5490-ISZR is a two-channel energy management analog front-end (AFE) manufactured by Cirrus Logic. It operates within a supply voltage range of 3 V to 3.6 V and supports an operating temperature range from -40 °C to +85 °C. The component is housed in a surface-mount SOIC-16 package. It functions as a dedicated integrated circuit for precise energy measurement applications, integrating necessary signal conditioning and conversion capabilities.

Feature Summary

• Integrates dual-channel analog front-end processing specifically designed for energy management systems.
• Provides complete signal conditioning and digitization for accurate power and energy calculations.
• Supports industrial-grade operational reliability across extended temperature environments.

Applications

• Two-channel energy metering systems
• Power quality monitoring devices
• Non-destructive testing control equipment requiring current detection

Procurement Notes

Verify the specific suffix ISZR against official datasheets to confirm reel packaging specifications. Ensure compatibility with the required 3V to 3.6V supply rails and SOIC-16 footprint during integration. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring simultaneous measurement of two distinct electrical channels. It serves as a direct replacement for legacy single-channel or older generation meters like the CS5466. Evaluate system requirements for digital interface compatibility and reference voltage configurations prior to implementation.

Part Context

This part belongs to the Cirrus Logic CS5490 series of analog front-ends. The series represents a specialized line of integrated circuits focused on high-precision energy measurement. The CS5490 family is widely recognized in the utility metering sector for its ability to simplify design while maintaining high accuracy standards.

Replacement Considerations

The CS5466 is identified as a discontinued predecessor recommended for replacement by the CS5490 series. Verify pinout and register compatibility when migrating designs from older single-channel architectures to this dual-channel solution.
