ADI AD8019AR

驱动器xDSL

Overview

The AD8019AR is a low cost xDSL line driver optimized to drive a minimum of 13 dBm into a 100 Ω load while delivering outstanding distortion performance. The AD8019AR is designed on a 24 V high-speed bipolar process enabling the use of ± 12 V power supplies or 12 V only. When operating from a single 12 V supply the highly efficient amplifier architecture can typically deliver 170 mA output current into low impedance loads through a 1:2 turns ratio transformer. Hybrid designs using ±12 V supplies enable the use of a 1:1 turns ratio transformer, minimizing attenuation of the receive signal. The AD8019AR typically draws 9 mA/ amplifier quiescent current. A 1-bit digital power down feature reduces the quiescent current to approximately 1.6 mA/amplifier.
