MPY534

Precision

ANALOG MULTIPLIER

DESCRIPTION

The MPY534 is a high accuracy, general purpose

four-quadrant analog multiplier. Its accurately laser

trimmed transfer characteristics make it easy to use in

a wide variety of applications with a minimum of

external parts and trimming circuitry. Its differential

X, Y and Z inputs allow configuration as multiplier,

squarer, divider, square-rooter and other functions

while maintaining high accuracy.

The wide bandwidth of this new design allows accu-

rate signal processing at higher frequencies suitable

for video signal processing. It is capable of performing

IF and RF frequency mixing, modulation and demodu-

lation with excellent carrier rejection and very simple

feedthrough adjustment.

An accurate internal voltage reference provides pre-

cise setting of the scale factor. The differential Z input

allows user selected scale factors from 0.1 to 10 using

external feedback resistors.
