FUNCTIONAL DESCRIPTION
The UZZ9001 is a mixed signal IC for angle measurement
systems. It combines two analog signals (sine and cosine)
into a linear output signal. The output stage implements
the Motorola Serial Peripheral Interface (SPI) protocol.
The UZZ9001 has been designed for use with the double
sensor KMZ41.
The analog measurement signals on the IC input are
converted to digital data with two ADC’s. The ADC’s are a
Sigma-Delta modulator employing a 4th order continuous
time architecture with an over-sampling ratio of 128 to
achieve high resolution. The converter output is a digital
bitstream with an over-sampling frequency of typically
500 kHz.
The bitstream is fed into a decimation filter which performs
both low pass filtering and down-sampling. The IC has two
input channels each of which has its own ADC and
decimation filter. The two decimation filter outputs are
15-bit digital words at a lower frequency of typically
3.9 kHz which is the typical sampling frequency of the
sensor system. The digital representations of the two
signals are then used to calculate the current angle. This
calculation is carried out using the so-called CORDIC
algorithm. The angle is represented with a 13-bit
resolution. An SPI compatible interface converts the
output word to the serial peripheral interface protocol.
