The ADLD8403 comprises two differential, high output current, low power consumption operational amplifiers. It is particularly well suited for the CO driver interface in digital subscriber line systems, such as ADSL and ADSL2+. The driver can deliver 20.4 dBm to a line while compensating for losses due to hybrid insertion and back termination resistors. The ADLD8403 uses the Analog Devices, Inc., second generation Adaptive Linear Power™ (Class H) architecture to achieve unprecedented power efficiency using a single power supply. Additional functionality allows the shutdown of pumps for enhanced power savings for line powers of less than 14.5 dBm. This functionality yields the smallest printed circuit board (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 ADLD8403 to be the CO line driver in ADSL and other xDSL systems.The ADLD8403 is available in a 4 mm × 4 mm, 20-lead LFCSP.
