General Description

The EL4393C is three wideband current-feedback amplifiers op­timized 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.
The EL4393C operates on supplies as low as

g

4V up tog15V.

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

g

1tog10 gain
range. The EL4393C has been optimized for use with 1300X
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.

All parameters having Min/Max specifications are guaranteed. The Test Level column indicates the specific device testing actually
performed during production and Quality inspection. Elantec performs most electrical tests using modern high-speed automatic test
equipment, specifically the LTX77 Series system. Unless otherwise noted, all tests are pulsed tests, therefore T
