DESCRIPTION

The THS6012 contains two high-speed drivers

capable of providing 400 mA output current (min) into

a 25 Ω load. These drivers can be configured

differentially to drive a 50-VPP output signal over lowimpedance

lines. The drivers are current feedback

amplifiers, designed for the high slew rates necessary

to support low total harmonic distortion (THD) in

xDSL applications. The THS6012 is ideally suited for

asymmetrical digital subscriber line (ADSL)

applications at the central office, where it supports

the high-peak voltage and current requirements of

this application.

Separate power supply connections for each driver

are provided to minimize crosstalk. The THS6012 is

available in the small surface-mount, thermally

enhanced 20-pin PowerPAD? package.
