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.
