Applications Information
The EL2082 is best thought of as a current-conveyor with variable current gain A current input to the
IIN pin will be replicated as a current driven out the IOUT pin with a gain controlled by VGAIN Thus
an input of 1 mA will produce an output current of 1 mA for VGAIN e 1V An input of 1 mA will
produce an output of 2 mA for VGAIN e 2V The useable VGAIN range is zero to a2V A negative level
on VGAIN even only b20 mV will yield very high signal attenuation

This resistor-load circuit shows a simple method of converting voltage signals to currents and vice
versa

RIN would typically be 1 kX for video level inputs or 10 kX for g10V instrumentation signals The
higher the value of RIN (the lower the input current) the lower the distortion levels of the EL2082 will
be An approximate expression of the nonlinearity of the EL2082 is
Nonlinearity (%) e 03 IIN (mA)2
Optimum input current level is a tradeoff between distortion and signal-to-noise-ratio The distortion
and input range do not change appreciably with VGAIN levels distortion is set by input currents alone
