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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The THS6012 incorporates a PowerPad on the underside of the chip. This acts as a heatsink and must be connected to a thermal
dissipation plane for proper power dissipation. Failure to do so can result in exceeding the maximum junction temperature, which could permanently damage the device. See the
Thermal Information
section of this document for more information about PowerPad
technology.
