450MHz Fixed Gain Amplifiers with Enable
The EL5108 and EL5308 are fixed gain amplifiers with a
bandwidth of 450MHz. This makes these amplifiers ideal for
today's high speed video and monitor applications. They
feature internal gain-setting resistors and can be configured
in a gain of +1, -1 or +2. The same bandwidth is seen in both
gain-of-1 and gain-of-2 applications.
The EL5108 and EL5308 also incorporate an enable and
disable function to reduce the supply current to 25A typical
per amplifier. Allowing the CE pin to float or applying a low
logic level will enable the amplifier.
The EL5108 is offered in the 6-pin SOT-23 and the industry-
standard 8-pin SO packages and the EL5308 is available in
the 16-pin SO and 16-pin QSOP packages. All operate over
the industrial temperature range of -40C to +85C.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
