Typical PLC Driver Application The AD8398 incorporates power management functionality via GENERAL DESCRIPTION two CMOS-compatible control pins, PD0 and PD1. These pins The AD8398 comprises two high-speed current feedback select one of four operating modes: full power, medium power, operational amplifiers. The high output current, high band- low power, and complete power down. In the power-down width, and fast slew rate make it particularly well suited as the mode, the quiescent current drops to 1.2 mA. line driver in VDSL and VDSL2 applications. The AD8398 is available in a thermally enhanced 4 mm × 4 mm, 16-lead LFCSP. The AD8398 operates in the extended industrial temperature range of −40°C to +85°C.
