General Description

The EL4393C is three wideband current-feedback amplifiers op-
timized for video performance Each amplifier can drive a load
of 150

X at video levels Each amplifier has a disable capability

which is controlled by a TTL CMOS compatible logic signal
The EL4393C operates on supplies as low as

4V up to

15V

Being a current-feedback design the bandwidth stays relatively
constant at approximately 80 MHz over the

1 to

10 gain

range The EL4393C has been optimized for use with 1300

feedback resistors at a gain of 2

When the outputs are disabled the supply current consumption
drops by about 4 mA per channel that is disabled This feature
can be used to reduce power dissipation
