AD8392AREZ

Overview

The AD8392AAREZ is a dual-port ADSL/ADSL+ line driver designed for high-performance digital subscriber line applications. It integrates two independent drivers capable of delivering 500 mA output current per channel into low-impedance loads. The device operates on a single supply voltage ranging from 10 V to 24 V, with a typical quiescent current of 5.8 mA. Key electrical specifications include a slew rate of 515 V/us, a 3 dB bandwidth of 37 MHz, and a common-mode rejection ratio (CMRR) of 63 dB. It features a power supply rejection ratio (PSRR) of 72 dB and an input bias current of 10 uA.

Feature Summary

• Dual-channel architecture optimized for ADSL and ADSL+ line driving requirements
• High peak output current capability of 500 mA per channel for robust signal transmission
• Integrated thermal shutdown protection to ensure reliability under fault conditions
• Low distortion performance suitable for high-speed data communication standards

Applications

• ADSL and ADSL+ modem line interface circuits
• Digital Subscriber Line Access Multiplexer (DSLAM) equipment
• Network interface cards requiring balanced line driving
• Telecommunications infrastructure for broadband access networks

Procurement Notes

Verify the specific suffix designation when ordering, as packaging options such as tube or reel configurations exist for the AD8392A series. Confirm that the required variant matches the intended application voltage and current specifications. Check for moisture sensitivity labeling and appropriate storage conditions prior to assembly. Ensure compatibility with the target PCB footprint, typically TSSOP-28 for this package type. Validate regulatory compliance status including RoHS directives for the specific manufacturing batch.

Selection Notes

Select the AD8392AAREZ when designing systems requiring simultaneous differential signaling for ADSL protocols. Consider the 24 V maximum supply limit and 500 mA current drive when sizing external components and heat dissipation strategies. Evaluate the 37 MHz bandwidth against the required data rates to ensure signal integrity. Compare the 63 dB CMRR against system noise immunity requirements. Assess the TSSOP-28 package constraints regarding thermal management and board space availability compared to alternative amplifier families.

Part Context

This component belongs to the Analog Devices AD8392A family of specialized amplifiers. It is categorized under special purpose amplifiers and specifically functions as a line driver for telecommunications. The device is part of the broader portfolio of integrated circuits supporting DSL technology, distinct from general-purpose operational amplifiers or RF modulators found in other product lines.

Replacement Considerations

Publicly confirmed direct substitutes are not explicitly listed in the provided documentation. Designers should consult official Analog Devices resources for cross-reference information. Verify pinout compatibility and electrical parameter equivalence before considering alternative manufacturers. Ensure that any replacement maintains the dual-channel configuration and sufficient output current capabilities.
