The AD8398 comprises two high-speed current feedback operational amplifiers.

The high output current, high band-width, and fast slew rate make it particularly well suited as the line driver in VDSL and VDSL2 applications.

The AD8398 is available in a thermally enhanced 4 mm × 4 mm, 16-lead LFCSP.

The AD8398 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, and complete power down. In the power-down mode, the quiescent current drops to 1.2 mA.

The AD8398 operates in the extended industrial temperature range of −40°C to +85°C.
