描述 Description

The THS6052/3 is a high-speed line driver ideal for driving signals from the remote terminal to the central office in asymmetrical digital subscriber line (ADSL) applications. It can operate from ±12-V supply voltages while drawing only 5.2 mA of supply current per channel. It offers low ?83 dBc total harmonic distortion driving a 100- load from a ±12-V supply. The THS6053 features a low-power shutdown mode, consuming only 300 uA quiescent current per channel. The THS6052/3 is packaged in a standard SOIC, SOIC PowerPAD?, and TSSOP PowerPAD? packages.
