TYPICAL APPLICATIONS
Figure 8 shows a device setup with an unipolar sensor Figure 9 shows a typical device setup with a sensor
signal. With the resistors R1, R2, R3, R4 and R5 it is being connected to the input stages via differential
possible to adjust to the sensor signal (compensation bridges. Index gating uses a differential bridge as well.
of amplitude, reference voltage, and sensor supply).
Note also that it is advisable to decouple the supply
voltage with a capacitor. Resistor sizes on pins CFG1
and CFG2 need to be chosen in accordance with the
desired operation mode. Refer to Table 6 for more de-
tails.

As a general rule our developments, IPs, principle circuitry and range of Integrated Circuits are suitable and specifically designed for appropriate use in technical
applications, such as in devices, systems and any kind of technical equipment, in so far as they do not infringe existing patent rights. In principle the range of
use is limitless in a technical sense and refers to the products listed in the inventory of goods compiled for the 2008 and following export trade statistics issued
annually by the Bureau of Statistics in Wiesbaden, for example, or to any product in the product catalogue published for the 2007 and following exhibitions in
Hanover (Hannover-Messe).
We understand suitable application of our published designs to be state-of-the-art technology which can no longer be classed as inventive under the stipulations
of patent law. Our explicit application notes are to be treated only as mere examples of the many possible and extremely advantageous uses our products can
be put to.
