AD8392AREZ-REEL

Overview

The AD8392A 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 with a slew rate of 515 V/us and a 3 dB bandwidth of 37 MHz. The device operates on a single supply voltage ranging from 10 V to 24 V, drawing 5.8 mA of quiescent current. Key electrical characteristics include a common-mode rejection ratio of 63 dB and a power supply rejection ratio of 72 dB. It features differential outputs and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• High peak output current capability of 500 mA per channel for robust signal transmission
• Differential output configuration ensures balanced signal integrity over twisted-pair lines
• Integrated thermal protection and short-circuit current limiting for enhanced reliability

Applications

• ADSL and ADSL+ modem line drivers
• VDSL system interface circuits
• Digital subscriber line access multiplexer (DSLAM) equipment
• Telecommunications network interface cards

Procurement Notes

Verify the specific suffix designation when sourcing components, as packaging variations such as tube versus reel configurations exist within the AD8392A series. Confirm that the received part matches the required package type, typically TSSOP-28, and validate compliance with relevant environmental standards. Ensure compatibility with existing board layouts regarding pin assignments and thermal dissipation requirements before integration into production designs.

Selection Notes

Select this component for applications requiring high current drive capabilities in DSL environments. The dual-channel design simplifies schematic layout by integrating both transmit and receive paths or multiple line interfaces into a single package. Consider the 10 V minimum supply requirement when designing power management sections. The device offers a balance of speed and power consumption suitable for residential and enterprise telecommunications gateways.

Part Context

The AD8392A belongs to Analog Devices' specialized amplifier family focused on telecommunication interface solutions. It addresses the need for compact, high-performance line drivers that replace discrete transistor implementations. This integration reduces board space and improves consistency in mass-produced DSL equipment. The device complements other analog front-end components used in broadband access networks.

Replacement Considerations

Publicly confirmed direct substitutes are not available in the provided documentation. When evaluating alternatives, ensure the replacement supports the same 500 mA output current and 10-24 V supply range. Verify that any substitute maintains the TSSOP-28 footprint and compatible control logic levels to facilitate drop-in replacement without significant redesign.
