AD8392ARE

GENERAL DESCRIPTION

The AD8392 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 is capable of providing enough power to deliver 20.4 dBm to a line, while compensating for losses due to hybrid insertion and back termination resistors. In addition, the low distortion, fast slew rate, and high output current capability make the AD8392 ideal for many other applications, including medical instrumentation, DAC output drivers, and other high peak current circuits.
