EL4095C
Video Gain Control Fader Multiplexer
General Description
The EL4095C is a versatile variable-gain building block At its
core is a fader which can variably blend two inputs together and
an output amplifier that can drive heavy loads Each input ap-
pears as the input of a current-feedback amplifier and with ex-
ternal resistors can separately provide any gain desired The
output is defined as
V
where A and B are the fed-back gains of each channel
Additionally two logic inputs are provided which each override
the analog V
and 0% for the other The logic inputs switch in only 25 ns and
provide high attenuation to the off channel while generating
very small glitches
Signal bandwidth is 60 MHz and gain-control bandwidth
20 MHz The gain control recovers from overdrive in only
70 ns
The EL4095C operates from
is available in both 14-pin DIP and narrow surface mount pack-
ages
