This document describes the features and characteristics of Single Port VDSL2 Line Driver with Shutdown AD8398A Rev. D, including voltage feedback, wide output swing, high output current, low distortion, and high speed.
The AD8398A is a high‑speed, voltage‑feedback operational amplifier configured as a single‑port VDSL2 line driver with shutdown capability. It is intended for ADSL2+, VDSL2, PLC and other twisted‑pair communication applications, operating from ±6 V or a single 12 V supply and supporting an industrial temperature range of –40 °C to +85 °C.
Key features include a wide 18.4 V p‑p differential output swing, 450 mA peak linear output current, 85 MHz –3 dB bandwidth, four selectable power‑control modes via PD0/PD1 pins, and a low 0.7 mA quiescent current in power‑down. The datasheet provides pin configurations, typical application circuits, board‑layout guidelines, thermal‑pad handling, and performance graphs such as multitone power ratio and noise characteristics.
