Overview
The AD8016ARE-REEL7, produced by Analog Devices Inc., is a 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, and proprietary xDSL systems. It operates on ±5 V to ±12 V voltage supplies and is known for its high output voltage and current drive capabilities, making it suitable for central office (CO) terminal applications.

Key Features
- Low power operation with a total supply current of 12.5 mA/amp (typical) and a power reduced keep-alive current of 4.5 mA/amp.
- High output voltage and current drive, with an output current of up to 600 mA and a differential output voltage of 40 V p-p.
- 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 with a bandwidth of 78 MHz (–3 dB) and a slew rate of 1000 V/μs.
- Flexible power-down modes controlled by two digital bits (PWDN0, PWDN1), allowing for full performance, keep-alive state, or two intermediate bias states.
- Robust thermal packaging with junction-to-case thermal resistance (θJC) of 5.6°C/W for the TSSOP-EP package and 8.6°C/W for the SO-Batwing package.
Applications
The AD8016 is designed for use in the line drive interface of various Digital Subscriber Line 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 applications due to its high output power and low distortion characteristics.
