ADE9112ARNZ-REEL

ADCs/DACs - Special Purpose Overview

The ADE9112ARNZ-REEL is an isolated, sigma-delta analog-to-digital converter manufactured by Analog Devices Inc. It features two fully differential 24-bit ADC channels with integrated isoPower isolation and a DC-to-DC converter. The device supports sample rates up to 32 kSPS, achieving signal-to-noise ratios of 83 dBFS for current channels and 91 dBFS for voltage channels at the maximum rate. It operates on a single 3.3 V supply and utilizes a 28-lead SOIC_W_FP package with an 8.3 mm creepage distance. The component includes bidirectional SPI communication with CRC verification and hardware interrupt capabilities.

ADCs/DACs - Special Purpose Feature Summary

• Integrated safety-certified galvanic isolation with isoPower DC-to-DC converter
• Two-channel simultaneous sampling 24-bit Sigma-Delta ADC architecture
• High precision with <13 ppm/°C reference drift and <2 nV/°C offset drift
• Bidirectional SPI interface with cyclic redundancy check (CRC) and daisy-chain support

ADCs/DACs - Special Purpose Applications

• Shunt-based polyphase energy meters
• Electric vehicle supply equipment
• DC metering systems
• Power quality monitoring devices
• Solar inverters

ADCs/DACs - Special Purpose Procurement Notes

Verify that the REEL suffix indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm compliance with RoHS directives and moisture sensitivity levels prior to assembly. Ensure storage conditions adhere to manufacturer guidelines to prevent degradation of the surface-mount device before soldering.

ADCs/DACs - Special Purpose Selection Notes

Select this model for applications requiring isolation between high-voltage measurement domains and low-voltage microcontrollers. It is suitable for designs needing only one voltage channel alongside current measurements. Consider the 28-lead wide-body package dimensions for PCB layout constraints and verify thermal dissipation requirements against the specified junction-to-ambient resistance values.

ADCs/DACs - Special Purpose Part Context

This component belongs to the ADE9103/ADE9112/ADE9113 family of precision energy metering ICs. While the ADE9113 offers three isolated channels and the ADE9103 provides non-isolated performance, the ADE9112 specifically addresses scenarios requiring dual-channel isolation with a single voltage input path. All variants share identical core ADC specifications and communication protocols.
