UZZ9000; Sensor Conditioning Electronic
| Description |  |
 |
The UZZ9000 is an integrated circuit which is able to
combine two sinusoidal signals (sin and cos) into one
single linear output signal. These signals might come from
magnetoresistive sensors. In that case this function can
provide good results as the signal conditioning electronic
for angle measurement forming from the output signal of
two magnetoresistive sensors. This gives the sin (a) and
the cos (a) of the angle to be measured a linear output
characteristic for angles up to 360°. This integrated circuit
can also be used for all other applications in which the sin
and the cos of a signal have to be transferred in one output
characteristic. A typical application would be any kind of
resolver application. The two primary input signals are
converted into the digital domain, with a CORDIC
algorithm performing the arctan transformation. Since
todays applications work typically with analog output
signals (e.g. potentiometers), the resulting signal which is
transferred back to the analog domain is a ratiometric one.
This integrated circuit enables the user to set both the
angle range to be measured (Fig.3a2 to a1 ) and the zero
point (Fig.3a1 ) in wide ranges. These ranges are
determined by an external voltage divider.
