The MAX9480/MAX9481/MAX9482 low-power, low-distortion, class-G, high-current asymmetric digital subscriber line (ADSL) drivers offer Rail-to-Rail output and are ideal for ADSL in central-office applications. Operating from 5V and 2.5V supplies, the drivers incorporate two high-speed current-feedback preamplifiers driving two fixed-gain class-G buffers. The buffers can deliver 20.4dBm average line power with a signal crest factor of 5.3, and are designed to be directly DC or AC bridged across a 1:2.5 transformer. The MAX9480/MAX9481/MAX9482 employ an active line termination scheme for incoming signals that eliminates the need for back-match resistors, reducing line-card power consumption at full rate to less than half of that required by conventional class-AB line-driver circuits.
