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 TTLCMOS compatible logic signal
The EL4393C operates on supplies as low as g4V up to g15V
Being a current-feedback design the bandwidth stays relatively
constant at approximately 80 MHz over the g1to g10 gain
range The EL4393C has been optimized for use with 1300
X
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
