Medium Power Differential Line Driver

The EL1519 is a dual operational amplifier designed for
customer premise line driving in DMT ADSL solutions. This
device features a high drive capability of 250mA while
consuming only 7.1mA of supply current per amplifier and
operating from a single 5V to 12V supply. This driver
achieves a typical distortion of less than -85dBc, at 150kHz
into a 25Ω load. The EL1519 is available in the industry
standard 8 Ld SO. This device is optimized to use low
feedback resistor values to minimize noise in ADSL
systems.

The EL1519 is ideal for ADSL, SDSL, HDSL2 and VDSL line
driving 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.
