GENERAL DESCRIPTION

The AD45048 ADSL CPE line driver is a dual operational

amplifier capable of driving high output current (230 mA); it

features a rail-to-rail output stage that swings to within 0.5 V

of the supply rails. The AD45048 rail-to-rail output stage

surpasses the output voltage capability of typical emitter-

follower output stages and can deliver up to 23 V p-p

differentially from a single 12 V supply in ADSL CPE line

driving applications. The low distortion, high output current

and wide output dynamic range make the AD45048 ideal for

driving upstream signals in ADSL CPE applications.

Fabricated with ADI’s high speed XFCB-HV (eXtra Fast

Complementary Bipolar-High Voltage) process, the high

bandwidth and fast slew rate of the AD45048 keep distortion to

a minimum while dissipating minimum power. The AD45048 is

available in a standard 8-lead SOIC package that can operate

from −40°C to +85°C.
