DESCRIPTION
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.
