AD8398A comprises two high speed, voltage feedback operational amplifiers. When configured as a differential line driver, the AD8398A is an ideal choice for ADSL2+, VDSL2, and power line communications (PLC) applications. It has high output current, high bandwidth, and fast slew rate, combined with exceptional multitone power ratio (MTPR) and common-mode stability.

The AD8398A incorporates power management functionality via two CMOS-compatible control pins, PD0 and PD1. These pins select one of four operating modes, full power, medium power, low power, or complete power-down. In the power-down mode, the quiescent current drops to 0.7mA.
