General Description
The EL5197C and EL5197AC are fixed gain amplifiers with a band-
width of 200MHz, making these amplifiers ideal for today's high
speed video and monitor applications. These amplifiers feature inter-
nal 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.
With a supply current of just 4mA 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 EL5197AC 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 EL5197C is offered in the 5-pin SOT23 package and the
EL5197AC is available in the 6-pin SOT23 as well as the industry-
standard 8-pin SO packages. Both operate over the industrial tempera-
ture range of -40C to +85C.
