FEATURES One chip angle sensor output signal conditioning 180° angle range with KMZ41 Accuracy better than 1° together with KMZ41 Temperature range from 40 to +150 °C SPI protocol 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.
