General Description

The 4083C makes use of an Elantec fully complimentary oxide isolated bipolar process to produce a patent pending current in, current out four quadrant multiplier. Input and output signal summing and direct interface to other current mode devices can be accomplished by simple connection to reduce component count and preserve bandwidth. The selection of an appropriate series resistor value allows an input to accept a voltage signal of any size and optimize dynamic range.
