• SO24 package.
GENERAL DESCRIPTION
The UZZ9001 is an integrated circuit that combines two
sinusoidal signals (sine and cosine) into one single linear
output signal. These signals might come from the
magnetoresistive sensor KMZ41. This results in a
measurement system for angles up to 180°. The
integrated circuit UZZ9001 can also be used for all other
applications in which an angle has to be calculated from a
sine and 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. The output
stage implements the Motorola Serial Peripheral Interface
(SPI) protocol.
