EL2082C Current-Mode Multiplier

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 impe.
