General Description
AD45048 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 emitterfollower 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.
