LINEAR ANALOG OUTPUT (LAO)
The LAO pin provides a linear analog output voltage
representing the actual position. The output voltage
can be either rail to rail or within a range of 10% to
90% of the supply voltage VDD, depending on the pro-
grammed configuration. In 10%-to-90% mode a short-
circuit with VDD or GND is recognizable.
The zero position therefore begins at the minimum volt-
age (either GND or 10% of VDD) and reaches its max-
imum (either VDD or 90% of VDD) at the selected an-
gular range limit (90°, 180°, 270° or 360°), depending
on the chosen configuration.
LAO is tristate when the device is disabled.
