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.
