EL5293, EL5293A
Dual 300MHz Current Feedback Amplifier
with Enable
The EL5293 and EL5293A represent dual current feedback
amplifiers with a bandwidth of 300MHz. This makes these
amplifiers ideal for today's high speed video and monitor
applications.
With a supply current of just 4mA per amplifier and the ability
to run from a single supply voltage from 5V to 10V, these
amplifiers are also ideal for hand held, portable or battery
powered equipment.
The EL5293A 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 EL5293 is offered in the industry-standard 8-pin SO
package and the space-saving 8-pin MSOP package. The
EL5293A is available in a 10-pin MSOP package and all
operate over the industrial temperature range of -40
C to
+85
C.

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.
