description
The THS6032 is a low-power line driver ideal for asymmetrical digital subscriber line (ADSL) applications. This
device contains two high-current, high-speed current-feedback drivers, which can be configured differentially
for driving ADSL signals at the central office. The THS6032 features a unique class-G architecture to lower
power consumption to 1.35 W. The THS6032 can also be operated in a traditional class-AB mode to reduce
the number of power supplies to two.
