ADE7913ARIZ-RL

ADCs/DACs - Special Purpose Overview

The ADE7913ARIZ-RL is a three-channel, isolated Sigma-Delta analog-to-digital converter designed for polyphase energy metering applications using shunt current sensors. It integrates an isoPower isolated DC-to-DC converter and iCoupler technology to provide signal and power isolation across a single barrier rated at 5000 V rms. The device features one current channel with a ±31.25 mV input range and two voltage channels with a ±500 mV input range. It operates on a single 3.3 V supply and communicates via a 4-wire SPI interface. The component is housed in a 20-lead wide-body SOIC package with 8.3 mm creepage distance.

ADCs/DACs - Special Purpose Feature Summary

• Three simultaneous sampling Σ-Δ ADCs: one current channel (67 dB SNR) and two voltage channels (72 dB SNR).
• Integrated isoPower isolated DC-to-DC converter eliminates external isolation components.
• Single 3.3 V supply operation with internal 1.2 V reference and on-chip temperature sensor.
• Safety approvals include UL 1577 recognition, CSA Component Acceptance Notice 5A, and DIN VDE V 0884-10 certification.

ADCs/DACs - Special Purpose Applications

• Shunt-based polyphase energy meters
• Power quality monitoring systems
• Solar inverters
• Industrial PLCs and process monitoring

ADCs/DACs - Special Purpose Procurement Notes

Verify the -RL suffix indicates reel packaging when sourcing. Confirm that the specific revision matches the required regulatory compliance levels, particularly regarding maximum working voltages under DIN VDE V 0884-10 standards. Ensure the ordering part number corresponds exactly to the Analog Devices manufacturer designation.

ADCs/DACs - Special Purpose Selection Notes

Select this model over the ADE7912 if three independent measurement channels are required. The ADE7913 provides two voltage channels and one current channel, whereas the ADE7912 offers only one voltage channel. Both share identical isolation specifications and package dimensions. Verify that the system clock frequency aligns with the specified 4.096 MHz XTAL1 input for optimal performance.

ADCs/DACs - Special Purpose Part Context

This component belongs to the ADE7912/ADE7913 family of isolated energy metering ICs. It utilizes Analog Devices' iCoupler and isoPower technologies to achieve total isolation in a compact form factor. The device is specifically engineered to replace traditional current transformers in shunt-based metering designs, reducing system size and cost while maintaining high accuracy.

ADCs/DACs - Special Purpose Replacement Considerations

The ADE7912ARIZ-RL is a compatible alternative within the same family but contains only two ADC channels (one voltage, one current). Direct pin-for-pin replacement is possible if the application requires fewer than three simultaneous measurements.
