7.2.5 Resolution of the Parameters

The programming parameters have a wide resolution of up to 14 bits.

Figure 8. Overview of the Angular Output Voltage

Figure 8 gives an overview of the different ranges. The failure bands are used to indicate a wrong operation of the AS5163. This can be caused

due to a broken supply line. By using the specified load resistors, the output level will remain in these bands during a fail. It is recommended to

set the clamping level CLL above the lower failure band and the clamping level CLH below the higher failure band.
