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.
