The AD8393 is a low power, high output current, single-supply, ADSL-CO line driver that features ADI’s patent pending Adaptive Linear Power architecture. It has 4 power modes, and can achieve over 36V p-p differential output while processing signals with occasional peaks.
The AD8393 is a low power, high output current, single-supply ADSL-CO line driver that features Analog Devices' patent pending Adaptive Linear Power (ALP) architecture. This 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 modulate internal driver supplies coincidentally with the peak voltages contained in Discrete Multitone (DMT) signals.
The device requires only a single 12 V power supply.
The amplifier can provide 20.4 dBm of line power from a single 12 V dc supply.
Crest factors up to 6.5 can be accommodated by the AD8393.
