AD8016ARBZ-REEL

Overview

The AD8016 is a dual-channel current feedback xDSL line driver designed for full-rate ADSL central office applications. It operates on ±5 V to ±12 V supplies, delivering up to 600 mA linear output current and 40 V p-p differential voltage into 50 Ω loads. Key electrical parameters include a 78 MHz bandwidth at G = +5, a 1000 V/μs slew rate, and -75 dBc single-tone distortion. Total supply current is typically 12.5 mA per amplifier, with flexible power-down states reducing consumption.

Feature Summary

• High-output current capability of 600 mA for driving low-impedance xDSL lines
• Integrated four-level digital power management via PWDN pins for optimized efficiency
• Current feedback architecture ensuring high speed and wide bandwidth
• On-chip thermal shutdown protection with alarm signal generation

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 against the datasheet ordering guide, as the AD8016 is available in 24-lead SOIC_W_BAT and 28-lead TSSOP_EP configurations. Confirm that the suffix indicates the correct tape-and-reel format if automated assembly is required. Ensure compatibility with CMOS logic levels for the power-down control inputs during integration.

Selection Notes

Select this component when designing xDSL interfaces requiring high peak currents and low distortion under moderate supply voltages. The device supports gain settings from +1 to +10 using recommended feedback resistor values. Consider the exposed paddle thermal performance and PCB copper area requirements to manage power dissipation effectively within the operating temperature range.

Part Context

Manufactured by Analog Devices Inc., the AD8016 utilizes a proprietary XFCB process to achieve high-speed performance in a compact surface-mount package. It serves as a specialized solution for broadband access infrastructure, replacing older discrete solutions or lower-performance amplifiers in modern DSLAM equipment designs.

Replacement Considerations

Public documentation lists the STLC60133 and MAX4142 as functional equivalents for xDSL line driving applications. Verify pinout compatibility and thermal characteristics before substitution, as packaging differences may require layout adjustments.
