THS6012IGQER

高速运算放大器 500-mA Dual Diff Line Driver

description

The THS6012 contains two high-speed drivers capable of providing 400 mA output current min into a 25 Ωload. 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.
