General Description
The EL2082 is a general purpose variable gain control building
block built using an advanced proprietary complementary bi-
polar 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 there-
fore the VIN pin can be used to reject common-mode noise and
establish an input ground reference The gain control input is
calibrated to 1 mAmA 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 mul-
tiple inputs can be summed and many outputs wire-or’ed or
mixed
The EL2082 operates from a wide range of supplies and is avail-
able in standard 8-pin plastic DIP or 8-lead SO
