• Description: Video Gain Control/fader/multiplexer
• Manufacturer: ETC-unknow

Applications Information
The EL4095 is a general-purpose two-channel
fader whose input channels each act as a current-
feedback amplifier (CFA) input Each input can
have its own gain factor as established by exter-
nal resistors For instance the Test Circuit shows
two channels each arranged as
traditional single feedback resistor R
from V
The EL4095 can be connected as an inverting
amplifier in the same manner as any CFA

Frequency Response
Like other CFA’s there is a recommended feed-
back resistor which for this circuit is 1 K
value of RF sets the closed-loop
width and has only a small range of practical
variation The user should consult the typical
performance curves to find the optional value of
R
width will decrease slightly as closed-loop gain is
increased R
bandwidth loss Too small a value of R
cause frequency response peaking and ringing
during transients On the other hand increasing
