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 ex-
tend the usable gain control range at high frequencies The bias
current is programmable to accommodate the voltage and pow-
er dissipation constraints of the package and available systems
The devices can implement all the classic four quadrant multi-
plier applications and are uniquely well suited to gain control
and signal summing of broadband signals
