EL5397A
Triple 200MHz Fixed Gain Amplifier with
Enable
The EL5397A 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
EL5397A features 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.
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 EL5397A 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.
For applications where board space is critical, the EL5397A
is offered in the 16-pin QSOP package, as well as a 16-pin
SO (0.150"). The EL5397A is specified for operation over the
full industrial temperature range of
-40
C to +85
C.
