250MHz/3mA Current Mode Feedback
Amplifier

The EL2480 is a quad current-feedback operational amplifier
which achieves a -3dB bandwidth of 250MHz at a gain of +1
while consuming only 3mA of supply current per amplifier. It
will operate with dual supplies ranging from ±1.5V to ±6V, or
from single supplies ranging from +3V to +12V. In spite of its
low supply current, the EL2480 can output 55mA while
swinging to ±4V on ±5V supplies. These attributes make the
EL2480 an excellent choice for low po wer and/or lo w v oltage
cable-driver, HDSL, or RGB applications.

For triple applications with disable, consider the EL2386 (16­pin triple).

NOTE: Intersil Pb-free 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.
