GENERAL DESCRIPTION

The 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 MTPR and common-mode stability. The

AD8398A is available in a thermally enhanced 4 mm × 4 mm,

16-lead LFCSP.

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 0.7 mA.

The AD8398A operates in the extended industrial temperature

range of −40°C to +85°C.
