General Description
The EL4393C is three wideband current-feedback amplifiers op-
timized for video performance. Each amplifier can drive a load
of 150X at video levels. Each amplifier has a disable capability,
which is controlled by a TTL/CMOS compatible logic signal.
# 80 MHz 3 dB bandwidth for
gains of 1 to 10
# 900 V/ms slew rate
# 10 MHz bandwidth flat to 0.1 dB
# Excellent differential gain and
phase

The EL4393C operates on supplies as low as 4V up to 15V.
Being a current-feedback design, the bandwidth stays relatively
# TTL/CMOS compatible

constant at approximately 80 MHz over the 1 to 10 gain
range. The EL4393C has been optimized for use with 1300X
feedback resistors at a gain of 2.
Applications
# RGB drivers
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.
# RGB multiplexers
# RGB gain blocks
# Video gain blocks
# Coax cable driver
# ADC drivers/input multiplexer
