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 instrumenta-
tion, DAC output drivers, and other high peak current circuits.
The AD8392 is available in two thermally enhanced packages, a
28-lead TSSOP/EP (AD8392ARE) and a 5 mm × 5 mm 32-lead
LFCSP (AD8392ACP). Four bias modes are available via the use
of two digital bits (PD1, PD0).

Additionally, the AD8392ACP provides V
COM
pins for on-chip
common mode voltage generation.
The low power consumption, high output current, high output
voltage swing, and robust thermal packaging enable the
AD8392 to be used as the CO line drivers in ADSL and other
xDSL systems, as well as other high current, single-ended or
differential amplifier applications.
