Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm the specific suffix 'RL' indicates reel packaging if required for assembly processes. Check current production status as discontinuation notifications may apply to legacy variants. Ensure environmental compliance documentation matches regional regulatory requirements for electronic components.

Selection Notes

Select this component for applications requiring high-accuracy single-phase energy measurement with simplified bill of materials due to the integrated oscillator. Consider the 16-lead NSOIC package constraints for PCB layout. Evaluate the 4.75 V to 5.25 V operating voltage against system power rails. Verify thermal performance within the -40 °C to +85 °C range for the intended environment.

Part Context

This part belongs to the AD71056 family of energy metering ICs from Analog Devices. It is designed for cost-effective, high-performance single-phase metering solutions. The integration of the oscillator reduces external component count compared to earlier generations requiring external crystal oscillators.

Replacement Considerations

Consult official Analog Devices documentation for qualified replacement parts or pin-compatible alternatives. Verify functional equivalence regarding oscillator integration and accuracy specifications before substitution.
