THS6182 - Texas Instruments

THS6182 LOW-POWER DISSIPATION ADSL LINE DRIVER

The THS6182 is a current feedback differential line driver ideal for full rate ADSL systems. Its extremely low-power dissipation is ideal for ADSL systems that must achieve high densities in ADSL central office rack applications. The unique architecture of the THS6182 allows the quiescent current to be much lower than existing line drivers while still achiev.
