AD8016ARP-REEL

Overview

The AD8016ARP-REEL is a low power, high output current xDSL line driver designed for central office applications. It operates on ±5 V to ±12 V supplies with a typical supply 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 at ±12 V. Key dynamic specifications 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 output
• Low single-tone distortion suitable for ADSL and HDSL2 systems

Applications

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

Procurement Notes

Verify the specific package type associated with the ARP suffix against the manufacturer's ordering guide, as the datasheet lists SOIC_W_BAT and TSSOP_EP options. Confirm that the REEL7 designation indicates tape and reel packaging if required by assembly processes. Check for end-of-life status or alternative recommendations from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring high current drive in xDSL applications where power efficiency is critical. The flexible power-down states allow optimization of quiescent current versus performance. Ensure adequate PCB copper area for thermal dissipation, as the device dissipates significant power when driving full downstream signals. Verify feedback resistor values to maintain stability and optimal multitone power ratio.

Part Context

The AD8016 is part of Analog Devices' high-speed operational amplifier portfolio, specifically engineered for broadband subscriber line interfaces. It addresses the need for robust drivers that can operate efficiently on standard voltage rails while meeting stringent distortion requirements for digital subscriber line technologies.

Replacement Considerations

Public documentation identifies the AD8016ARBZ and AD8016AREZ as functional equivalents within the same family. When substituting, verify pin compatibility between the SOIC_W_BAT and TSSOP_EP packages if the physical footprint differs. Ensure that the replacement part meets the same thermal and electrical specifications for the target application.
