General Description

The EL5397C is a triple channel, fixed gain amplifier with a band­width of 200MHz, making these amplifiers ideal for today’s high
speed video and monitor applications. The EL5397C features integnal
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 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.

For applications where board space is critical, the EL5397C is offered
in the 16-pin QSOP package, as well as a 16-pin SO. The EL5397C is
specified for operation over the full industrial temperature range of ---

-40°C to +85°C.
