(1) The absolute maximum ratings under any condition is limited by the constraints of the silicon process. Stresses above these ratings may cause permanent damage. Exposure to absolute-maximum-rated conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those ispecified is not implied.
(2) The maximum junction temperature for continuous operation is limited by package constraints. Operation above this temperature may result in reduced reliability and/or lifetime of the device.

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 achieving high linearity without the need for excess open loop gain.Fixed multiple bias settings of the amplifiers allow for enhanced  power savings for line lengths where the full performance of the amplifier is not required. To allow for even more flexibility and power savings, an I_ADJ pin is available to further lower the bias currents while maintaining stable operation with as little as 1.8 mA per channel. The wide output swing of 44 Vpp differentially with ±12-V power supplies allows for more dynamic headroom, keeping distortion at a minimum. With a low 3.2 nV/HZ voltage noise coupled with a low 10 pA/HZ inverting current noise, the THS6182 increases the sensitivity of the receive signals, allowing for better margins and reach.
