THS6182D

功耗低ADSL线路驱动器 LOW-POWER DISSIPATION ADSL LINE DRIVER

The is a low power dissipation current-feedback 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 driver 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 IADJ pin is available to further lower the bias currents while maintaining stable operation with as little as 1.8mA per channel. The wide output swing of 44VPP differentially with ±12V power supplies allows for more dynamic headroom, keeping distortion at a minimum.
