AD8398AACPZ-R7

ADSL Driver Dual 16Pin LFCSP EP T/R

Product Details

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 extended industrial temperature range of −40°C to +85°C.
