CS5490-ISZ

Overview

The CS5490-ISZ is a two-channel analog front-end integrated circuit designed for energy management applications. 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 utilizes a surface-mount SOIC-16 package configuration.

Feature Summary

• Integrates dual delta-sigma analog-to-digital converters for simultaneous channel processing
• Includes on-chip programmable gain amplifiers and reference voltage sources
• Provides digital filtering capabilities for precise signal conditioning

Applications

• Single-phase energy metering systems
• Two-phase power monitoring devices
• Smart grid measurement infrastructure

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the source provides valid traceability for RoHS compliance status. Confirm that the SOIC-16 package dimensions match the target PCB footprint requirements before finalizing acquisition decisions.

Selection Notes

Select this component when designing systems requiring high-precision simultaneous measurement of multiple electrical parameters. The integrated architecture reduces external component count compared to discrete solutions. Evaluate thermal performance constraints relative to the specified industrial temperature range during layout planning.

Part Context

This device belongs to the Cirrus Logic CS5490 series of analog front-ends. It serves as a direct replacement for legacy components such as the CS5466 in existing designs. The series focuses on providing accurate energy measurement with minimal external support circuitry.

Replacement Considerations
