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 V_PP differentially with ±12-V power supplies allows for more dynamic headroom, keeping distortion at a minimum. With a low 3.2 nV/Hz inverting current noise, the THS6182 increases the sensitivity of the receive signals, allowing for better margins and reach.
