The ADLD8404 is comprised of two differential, high output current, low power consumption operational amplifiers. It is particularly well suited for the CO & FTTX driver interface in digital subscriber line systems, such as ADSL2+ and VDSL2. The driver can deliver 20.4 dBm to a line while compensating for losses due to hybrid insertion and back-termination resistors. ADLD8404 uses second-generation Adaptive Linear Power (Class H) architecture to achieve unprecedented power efficiency while using a single power supply and three external capacitors. Further functionality permits the shutdown of pumps for enhanced power savings for line power < 14.5 dBm. This yields the smallest PCB footprint and lowest total cost of ownership.
The low power consumption, high output current, high output voltage swing, and robust thermal packaging enable the ADLD8404 to be the CO or FTTX line driver in ADSL2+ and VDSL2 systems.
The ADLD8404 is available in a 4 mm × 4 mm 24-lead LFCSP.
