描述 Description

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. The differential outputs offer significant performance improvements which greatly extend the usable gain control range at high frequencies. The bias current is programmable to accommodate the voltage and power dissipation constraints of the package and available systems
supplies.
