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 multitone power ratio (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 industrial temperature range of
40°C to +85°C.
