EL4393
Triple 80MHz Video Amplifier w/Disable
The EL4393 is three wideband current-
feedback amplifiers optimized for video
performance. Each amplifier can drive
a load of 150
at video levels. Each amplifier has a disable
capability, which is controlled by a TTL/CMOS compatible
logic signal. The EL4393 operates on supplies as low as 4V
up to 15V.
Being a current-feedback design, the bandwidth stays rela-
tively constant at approximately 80MHz over the 1 to 10
gain range. The EL4393 has been optimized for use with
1300
feedback resistors at a gain of 2.
When the outputs are disabled, the supply current consump-
tion drops, by about 4mA per channel that is disabled. This
feature can be used to reduce power dissipation.
