LOW-POWER ADSL CENTRAL-OFFICE LINE DRIVER

description

The class-G architecture supplies current to the load from four supplies. For low output voltages (typically

the THS6032 output stages for high crest factor ADSL signals.

The THS6032 features a low-impedance shutdown mode, which allows the central office to receive incoming

calls even after the device has been shut down. The THS6032 is available packaged in the patented PowerPAD

package. This package provides outstanding thermal characteristics in a small-footprint surface-mount

package, which is fully compatible with automated surface-mount assembly procedures. It is also available in

designs.

Shutdown (SHDN1 and SHDN2) allows for powering down the internal circuitry for power conservation or for

multiplexing. Separate shutdown controls are available for each channel on the THS6032. The control levels

are TTL compatible. When turned off, each driver output is placed in a low impedance state which is determined

by the voltage at DGND. This virtual ground at the outputs allows proper termination of a transmission line.
