Description
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 1 mA 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-lead SO Connection Diagram 8-Pin DIP SO Top View 2082 – 1 January 1996 Rev D Note All.
