Procurement Notes

Verify availability status as distribution channels may indicate limited stock or restricted sales regions. Confirm that the specific suffix P48 corresponds to the required package variant and temperature rating. Ensure compatibility with existing board layouts for the 32-SQFN footprint before ordering. Check for any recent lifecycle notices regarding obsolescence or last-time buy notifications from the manufacturer.

Selection Notes

Select this component when designing single-phase metering solutions requiring integrated processing and high-resolution signal acquisition. The 22-bit ADC resolution is critical for accurate energy measurement in low-current scenarios. Consider the 5 MHz clock speed for real-time processing requirements. Ensure the design accommodates the 3.3 V operating voltage and utilizes the available GPIO pins for peripheral interfacing.

Part Context

This part belongs to the 78M6613 series of metering SoCs from Analog Devices / Maxim Integrated. These devices are designed to simplify the development of compliant energy meters by integrating necessary digital and analog functions into a single chip. The series typically targets utility metering applications where accuracy and integration density are paramount.

Replacement Considerations

Check for other variants within the 78M6613 family that may offer different pin counts or package types. Verify if alternative single-phase metering ICs from the same manufacturer provide similar ADC resolutions and core architectures.
