GENERAL DESCRIPTION
The AD8390 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+.
While in full bias operation, the
driver is capable of providing 24.4 dBm output power into low
resistance loads. This is enough to power a 20.4 dBm line while
compensating for losses due to hybrid insertion, transformer
insertion, and back termination resistors.
The AD8390 fully differential amplifier is available in a ther-
mally enhanced lead frame chip scale package (LFCSP-16) and
a 16-lead QSOP/EP. Significant control and flexibility in bias
current have been designed into the AD8390. The four power
modes are controlled by two digital bits,
PWDN (1,0
) which
provide three levels of driver bias and one powered-down state.
In addition, the I
ADJ
pin can be used for fine quiescent current
trimming to tailor the performance of
the AD8390.

The low power consumption, high output current, high output
voltage swing, and robust thermal packaging enable the AD8390
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.
