The EL2082 is a general purpose variable gain control
building block, built using an advanced proprietary
complementary bipolar process. It is a two-quandrant
multiplier, so that zero or negative control voltages do not
allow signal feedthrough and very high attenuation is
possible. The EL2082 works in current mode rather than
voltage mode, so that the input impedance is low and the
output impedance is high. This allows very wide bandwidth
for both large and small signals.
The IIN pin replicates the voltage present on the VIN pin;
therefore, the VIN pin can be used to reject common-mode
noise and establish an input ground reference. The gain
control input is calibrated to 1mA/mA signal gain for 1V of
control voltage. The disable pin (E) is TTL-compatible, and
the output current can comply with a wide range of output
voltages.
Because current signals rather than voltages are employed,
multiple inputs can be summed and many outputs wire-or'ed
or mixed.
The EL2082 operates from a wide range of supplies and is
available in standard 8-pin plastic DIP or 8-pin SO.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: TJ = TC = TA
