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.
