AD8016ARB-REEL

Overview

The AD8016ARB-REEL is a low power, high output current xDSL line driver designed for ADSL central office applications. It operates on ±5 V to ±12 V supplies with a typical quiescent current of 12.5 mA per amplifier. The device delivers 600 mA linear output current and supports a 40 V p-p differential output swing into 50 Ω loads. Key performance metrics include a 78 MHz bandwidth at G = +5, a 1000 V/μs slew rate, and –75 dBc single-tone distortion at 1 MHz.

Feature Summary

• Integrated digital power management with four programmable bias levels via PWDN logic inputs
• High output current capability of 600 mA for driving low resistance loads
• On-chip thermal shutdown protection with alarm signal generation
• CMOS compatible logic inputs for flexible system integration

Applications

• ADSL central office (CO) terminal drivers
• HDSL2 line interface circuits
• VDSL system transceivers
• Proprietary xDSL line drivers

Procurement Notes

Verify the specific package variant, as the AD8016 is available in both 24-lead SOIC_W_BAT and 28-lead TSSOP_EP configurations. Confirm that the ordering suffix corresponds to the required reel quantity and tape-and-reel specifications. Ensure compatibility with the intended PCB footprint regarding the exposed paddle or NC pins depending on the selected package type.

Selection Notes

Select this component for designs requiring full ADSL CO performance on lower voltage rails such as ±12 V. Evaluate the trade-off between MTPR performance and power efficiency when utilizing the reduced bias states. Ensure adequate PCB copper area for thermal dissipation, as the device dissipates significant power during high-output operation. Verify feedback resistor values to maintain stability and optimal gain flatness.

Part Context

This part belongs to the Analog Devices AD8016 family of high-speed current feedback amplifiers. It is specifically optimized for digital subscriber line applications where high output drive and low power consumption are critical. The device integrates advanced power management features not typically found in standard operational amplifiers, allowing for dynamic adjustment of quiescent current based on system requirements.

Replacement Considerations

Public confirmed substitutes include the MAX4142 and MAX4147 from Maxim Integrated, which offer similar high-speed, high-output current characteristics for differential line driving. Intersil devices such as the ISL1556 and ISL1557 are also documented as xDSL differential line drivers. Verify pinout compatibility and thermal performance before substitution.
