GENERAL DESCRIPTION
O The AD8396 is comprised of four 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
S _{20.4 dBm to a line while compensating for losses due to hybrid}
insertion and back-termination resistors.
The low power consumption, high output current, high output
B ^{voltage swing, and robust thermal packaging enable the AD8396 to}
be used as the CO line driver in ADSL and other xDSL systems.
O ^{The AD8396 is available in a 4 mm × 4 mm 16-lead LFCSP.}
