ISL1558
FN6477.0
xDSL Differential Line Driver
The ISL1558 is a quad operational amplifier designed for
VDSL2 and ADSL2+ line driving in DMT based solutions.
This device features a high drive capability of 750mA while
consuming only 6mA of supply current per amplifier at low
bias and operating from a single 4.5V to 12V supply. The
driver achieves a typical distortion of -80dBc, at 200kHz into
a 50Ω differential load.
The ISL1558 is available in the thermally-enhanced
24 Ld QFN package and is specified for operation over the
full -40°C to +85°C temperature range. The ISL1558 has
control pins C₀ and C₁ for controlling the bias and
enable/disable of the outputs. These controls allow for
lowering the power to fit the performance/power ratio for the
application.
The ISL1558 is ideal for VDSL2 and ADSL2+ central office
line driving applications, including both 14.5dBm and 21dBm
applications.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
