CS5460C-ISZ

Sensor And Detector Interfaces Overview

The CS5460C-ISZ is a single-phase bi-directional power and energy integrated circuit manufactured by Cirrus Logic. It integrates two delta-sigma analog-to-digital converters (ADCs), high-speed power calculation functions, and a serial interface on one chip. Designed for residential metering, it accurately measures active energy, instantaneous power, IRMS, and VRMS. The device features a 2.5V internal reference with low drift, supports ground-referenced signals, and includes a watchdog timer and power supply monitor.

Sensor And Detector Interfaces Feature Summary

• Integrates dual delta-sigma ADCs and dedicated hardware for calculating energy and power metrics.
• Provides high linearity accuracy across a wide dynamic range without external calibration components.
• Includes an on-chip voltage reference and signal conditioning optimized for shunt sensor interfaces.

Sensor And Detector Interfaces Applications

• Single-phase 2-wire or 3-wire residential electricity meters
• Bi-directional power monitoring systems
• Energy data logging devices

Sensor And Detector Interfaces Procurement Notes

Verify the specific suffix 'ISZ' against the manufacturer's current datasheet to confirm package type and temperature grade. Check for obsolescence status as Cirrus Logic has discontinued several variants in this series. Ensure compatibility with the required SPI interface timing and voltage levels during integration.

Sensor And Detector Interfaces Selection Notes

Select this component for applications requiring precise measurement of active energy and RMS values in single-phase systems. It is suitable where minimizing external passive components is critical. Compare against newer generations if higher sampling rates or multi-phase capabilities are needed.

Sensor And Detector Interfaces Part Context

This part belongs to the CS5460 family of highly integrated power monitoring ICs. It is designed to replace discrete ADC and microcontroller solutions in traditional electromechanical meter designs. The CS5460C variant typically denotes a specific commercial temperature range and package configuration within the broader product line.

Sensor And Detector Interfaces Replacement Considerations

Direct replacements may include the CS5460A-BSZ or CS5460A-ASZ. Verify pinout compatibility and register mapping before substitution. Newer alternatives like the CS5463 offer enhanced features but may require software adjustments.
