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.
