Overview
The AD8016ARE, produced by Analog Devices Inc., is a high-performance, low-power, high-output current xDSL line driver. This dual amplifier is specifically designed for the line drive interface in Digital Subscriber Line (DSL) systems, including ADSL, HDSL2, VDSL, and proprietary xDSL systems. Operating from ±12 V supplies, the AD8016ARE offers low power dissipation and high output current, making it an ideal choice for central office (CO) terminal drivers.

Key Features
- Low power operation with total supply current of 12.5 mA/amp (typical) and power reduced keep-alive current of 4.5 mA/amp.
- High output voltage and current drive, with 600 mA output current and 40 V p-p differential output voltage.
- Low single-tone distortion of –75 dBc @ 1 MHz and high multitone power ratio (MTPR) of –75 dBc from 26 kHz to 1.1 MHz.
- High speed performance with 78 MHz bandwidth (–3 dB) and 1000 V/μs slew rate.
- Flexible power-down modes controlled by two digital bits (PWDN0, PWDN1), allowing full performance, output keep-alive state, or two intermediate bias states.
- Robust thermal packaging available in 24-lead SOIC_W_BAT, 20-lead PSOP3, and 28-lead TSSOP_EP with an exposed lead frame (ePAD).
Applications
The AD8016ARE is designed for use in various Digital Subscriber Line (DSL) systems, including:
- ADSL (Asymmetric Digital Subscriber Line)
- HDSL2 (High-bit-rate Digital Subscriber Line 2)
- VDSL (Very-high-bit-rate Digital Subscriber Line)
- Proprietary xDSL systems
It is particularly suited for central office (CO) terminal drivers due to its high output current, low power dissipation, and robust thermal packaging.
