The ISL1556 is a dual operational amplifier designed for
VDSL and ADSL line driving in DMT based solutions. This
device features a high drive capability of 350mA while
consuming only 4.5mA of supply current per amplifier and
operating from a single 4.5V to 12V supply. The driver
achieves a typical distortion of -80dBc, at 150kHz into a 25
load.
The ISL1556 is available in the thermally-enhanced
16 Ld QFN package and is specified for operation over the
full -40°C to +85°C temperature range. The ISL1556 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 ISL1556 is ideal for ADSL2+, SDSL, HDSL2 and VDSL
line driving applications, including both 14.5dBm and
17.5dBm 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.
