AD8016ARE

Overview

The AD8016ARE is a dual-channel, low-power, high-output current operational amplifier designed for xDSL line driver applications. It operates on dual supplies ranging from ±3 V to ±13 V. Key electrical parameters include a typical slew rate of 1000 V/μs and a -3 dB bandwidth of 78 MHz at a gain of +5. The device delivers up to 600 mA of linear output current and features programmable power-down states via digital logic inputs.

Feature Summary

• High output current capability suitable for driving low resistance loads in DSL systems
• Integrated digital power management with four user-programmable bias levels
• Current feedback architecture providing constant bandwidth across gain settings
• On-chip thermal shutdown protection with alarm signal output

Applications

• ADSL central office line drivers
• HDSL2 interface circuits
• VDSL system drivers
• Proprietary xDSL terminal equipment

Procurement Notes

Verify the package type matches the design requirements, as the AD8016 is available in both 24-lead SOIC_W_BAT and 28-lead TSSOP_EP configurations. Confirm that the specific suffix indicates the correct pinout and thermal characteristics. Ensure compatibility with the required supply voltage range and logic levels for the power-down control pins before integration.

Selection Notes

Select this component when high output current drive is required alongside low power consumption in broadband subscriber line applications. The current feedback topology ensures stable bandwidth regardless of gain setting. Consider the available power-down modes for efficiency optimization in customer premise equipment or central office terminals where thermal management is critical.

Part Context

This device belongs to Analog Devices' family of high-speed, high-current operational amplifiers tailored for telecommunications infrastructure. It addresses the specific needs of digital subscriber line systems by combining significant output drive capability with efficient power management features within a compact surface-mount package.

Replacement Considerations

Publicly confirmed substitutes are not identified in the provided documentation. When evaluating alternatives, ensure the replacement supports the required ±12 V operation, maintains comparable output current capabilities, and offers similar power-down functionality for xDSL applications.
