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-Vp-p output signal over

low-impedance 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.
