EL4095
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 external resistors. For instance, the Test
Circuit shows two channels each arranged as +1 gain, with
the traditional single feedback resistor RF connected from
VOUT to the -VIN of each channel.
The EL4095 can be connected as an inverting amplifier in
the same manner as any CFA.
Frequency Response
Like other CFAs, there is a recommended feedback resistor,
which for this circuit is 1kΩ. The value of RF sets the closed-
loop -3dB bandwidth, and has only a small range of practical
variation. The user should consult the typical performance
curves to find the optional value of RF for a given circuit gain.
In general, the bandwidth will decrease slightly as closed-
loop gain is increased; RF can be reduced to make up for
bandwidth loss. Too small a value of RF will cause frequency
response peaking and ringing during transients. On the other
hand, increasing RF will reduce bandwidth but improve
stability.
