• On-chip non-volatile memory for storing calibration coefficients and configuration settings
• SPI-compatible serial interface for system control and data retrieval

Applications

• Single-phase smart electricity meters
• Multi-phase energy monitoring systems
• Sub-metering applications in commercial buildings
• Industrial power quality analyzers

Procurement Notes

Verify the specific suffix 'ARIZ-RL' against the official Analog Devices datasheet to confirm package type, temperature range, and tape-and-reel specifications. Confirm end-of-life status or discontinuation notifications if sourcing from secondary markets. Ensure compliance with RoHS and REACH directives as stated in the manufacturer's documentation before procurement.

Selection Notes

Select this component when high accuracy in energy measurement is required without external multiplexers. Evaluate the need for integrated calibration storage versus external EEPROM solutions. Consider the SPI interface speed and pin count compatibility with the target microcontroller. Verify that the operating temperature range meets the environmental requirements of the final application.

Part Context

This part belongs to the AD711x series of energy metering ICs from Analog Devices. The series is characterized by its ability to provide precise measurements for utility-grade applications. The AD71163 variant specifically targets applications requiring comprehensive power parameter calculation within a compact form factor, reducing bill-of-materials complexity compared to discrete solutions.

Replacement Considerations

Consult the Analog Devices product change notification (PCN) database for officially confirmed substitute part numbers. Generic equivalents are not recommended due to strict calibration and accuracy requirements in energy metering. Verify pinout and register compatibility if considering alternative models within the same family.
