FEATURES
GENERAL DESCRIPTION
The UZZ9000 is an integrated circuit that combines two
sinusoidal signals (sine and cosine) into one single linear
output signal. When used in conjunction with the
magnetoresistive sensor KMZ41 it provides a
measurement system for angles up to 180 . The UZZ9000
can also be used for other applications in which an angle
has to be calculated from a sine and a cosine signal.
A typical application would be any kind of resolver
application.
The two input signals are converted into the digital domain
with two separate AD-converters. A CORDIC algorithm
performs the inverse tangent transformation. Since today’s
applications typically require analog output signals
(e.g. potentiometers), the resulting signal is transferred
back to the analog domain.
The UZZ9000 enables the user to set both the angle range
and the zero point offset. These ranges are set by external
voltage dividers.
