The AD8393 is a low power, high output current, single-supply, ADSL-CO line driver that features ADI's patent pending Adaptive Linear Power (ALP) architecture. The AD8393 ALP architecture offers increased port density in ADSL Central Office (CO) line card designs through improved line driver efficiency and simplified system design by operating from a single 12 V supply. The AD8393 ALP amplifier can provide 20.4 dBm of line power from a single 12 V dc supply, surpassing the efficiency of typical class AB line drivers. ADSL signals applied to the inputs of the AD8393 modulate internal driver supplies coincidentally with the peak voltages contained in Discrete Multitone (DMT) signals. The internal supplies modulated by the ALP circuit allow the AD8393 to operate from a lower supply voltage that improves efficiency and simplifies CO line card designs. Crest factors (CF) up to 6.5 can be accommodated by the AD8393.
