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 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.
