ADE7932ARIZ-RL

ADCs/DACs - Special Purpose Overview

The ADE7932ARIZ-RL is an isolated, 3-channel sigma-delta analog-to-digital converter (ADC) designed for polyphase energy metering applications utilizing shunt current sensors. It features one dedicated channel for measuring voltage across the shunt and a second channel for voltage sensing via resistor dividers. The device incorporates isoPower technology, providing an integrated isolated DC-to-DC converter that eliminates the need for external isolation blocks. It operates on a single 3.3 V supply and supports IEC 62053 standards.

ADCs/DACs - Special Purpose Feature Summary

• Isolated 3-channel Sigma-Delta ADC with integrated isoPower DC-to-DC converter
• High accuracy: less than 0.2% error in active/reactive energy over 2000:1 dynamic range
• Supports EN 50470-1/3, IEC 62053-21/22/23, and ANSI C12.20 standards
• Flexible digital interfaces including SPI, I2C, and HSDC for communication with ADE7978

ADCs/DACs - Special Purpose Applications

• Shunt-based polyphase meters
• Power quality monitoring systems
• Solar inverters
• Industrial PLCs with isolated sensor interfaces

ADCs/DACs - Special Purpose Procurement Notes

Verify the -RL suffix indicates reel packaging when sourcing components. Confirm availability through authorized distributors as stock levels fluctuate. Ensure compliance with RoHS directives and check humidity sensitivity等级 (MSL) requirements for surface mount assembly processes.

ADCs/DACs - Special Purpose Selection Notes

Select the ADE7932ARIZ-RL when two measurement channels are required per phase. Choose this model over the ADE7933 if only one current and one voltage channel are needed per phase. Ensure the design utilizes the ADE7978 master chip for full chipset functionality and data processing.

ADCs/DACs - Special Purpose Part Context

The ADE7932ARIZ-RL belongs to the ADE79xx series of isolated energy metering chipsets. It functions as a slave ADC paired with the ADE7978 multifunction energy metering IC. This configuration allows for accurate measurement of three-phase electrical energy using shunts while maintaining galvanic isolation between high-voltage lines and low-voltage logic.

ADCs/DACs - Special Purpose Replacement Considerations

The ADE7933ARIZ-RL serves as a direct functional replacement if three channels (one current, two voltage) are required instead of two. Both devices share identical isolation specifications and interface protocols within the ADE7978 ecosystem.
