GENERAL DESCRIPTION

The AD8390A is a high output current, low power consumption

differential amplifier. It is particularly well suited for the central

office (CO) driver interface in digital subscriber line systems

such as ADSL and ADSL2+. In full bias operation, the driver

delivers 20.4 dBm output power into low resistance loads while

compensating for hybrid and transformer insertion losses and

back termination resistors.

The AD8390A is available in a thermally enhanced LFCSP

package (16-lead LFCSP). Significant control and flexibility

in bias current have been designed into the AD8390A.

current trimming to tailor the performance of the AD8390A.

The low power consumption, high output current, high output

voltage swing, and robust thermal packaging enable the

AD8390A to be used as the central office line driver in ADSL,

ADSL2+, and proprietary xDSL systems, as well as in other high

current applications requiring a differential amplifier.
