MPY534 pdf datasheet (Precisio

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 accurate
signal processing at higher frequencies suitable
for video signal processing. It is capable of performing
IF and RF frequency mixing, modulation and demodulation
with excellent carrier rejection and very simple
feedthrough adjustment.
An accurate internal voltage reference provides precise
setting of the scale factor. The differential Z input
allows user selected scale factors from 0.1 to 10 using
external feedback resistors.
