EL5191, EL5191A
1GHz Current Feedback Amplifier with
Enable
The EL5191 and EL5191A amplifiers are of the current
feedback variety and exhibit a very high bandwidth of 1GHz.
This makes these amplifiers ideal for today's high speed
video and monitor applications, as well as a number of RF
and IF frequency designs.
With a supply current of just 9mA and the ability to run from
a single supply voltage from 5V to 10V, these amplifiers offer
very high performance for little power consumption.
The EL5191A also incorporates an enable and disable
function to reduce the supply current to 100A typical per
amplifier. Allowing the CE pin to float or applying a low logic
level will enable the amplifier.
The EL5191 is offered in the 5-pin SOT-23 package and the
EL5191A is available in the 6-pin SOT-23 as well as the
industry-standard 8-pin SO packages. Both operate over the
industrial temperature range of -40C to +85C.

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.
