ADE7913ARIZ

ADCs/DACs - Special Purpose Overview

The ADE7913ARIZ 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 utilizes iCoupler technology for data and power isolation. The device features one current channel with a ±31.25 mV peak input range and two voltage channels with a ±500 mV peak input range. It operates on a single 3.3 V supply, supports up to 8 kSPS sampling rates, and provides a 67 dB SNR for the current channel and 72 dB for voltage channels over a 3 kHz bandwidth. The component is housed in a 20-lead wide-body SOIC package with 8.3 mm creepage.

ADCs/DACs - Special Purpose Feature Summary

• Three isolated Sigma-Delta ADCs: one current channel (±31.25 mV) and two voltage channels (±500 mV)
• Integrated isoPower isolated DC-to-DC converter eliminating external isolation blocks
• 4-wire SPI serial interface for configuration and data readout
• On-chip temperature sensor and internal 1.2 V reference

ADCs/DACs - Special Purpose Applications

• Shunt-based polyphase energy meters
• Power quality monitoring systems
• Solar inverters
• Process monitoring equipment
• Industrial PLCs

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and environmental compliance. Confirm that the procurement source provides valid regulatory approvals such as UL recognition and VDE certification for safety-critical installations.

ADCs/DACs - Special Purpose Selection Notes

Select the ADE7913ARIZ when three isolated measurement channels are required for polyphase applications. Ensure the system design accommodates the 3.3 V supply requirement and the 20-lead wide-body SOIC footprint. Verify that the application voltage does not exceed the maximum working insulation voltage limits defined in the datasheet for the desired insulation lifetime.

ADCs/DACs - Special Purpose Part Context

The ADE7913ARIZ belongs to the ADE7912/ADE7913 family of isolated energy metering ICs from Analog Devices. While the ADE7912 offers two channels, the ADE7913 provides three channels, making it suitable for complete three-phase measurements. Both devices share identical isolation technologies and peripheral specifications.

ADCs/DACs - Special Purpose Replacement Considerations

The ADE7912 serves as a functional alternative if only two isolated channels are needed. No other direct cross-model replacements are documented in the provided source material.
