Revision 2.10

4 - 33

Pin 12 allows a single wire output of the 10-bit absolute position value. The value is encoded into a pulse width

modulated signal with 1µs pulse width per step (1µs to 1024µs over a full turn). By using an external low pass filter,

the digital PWM signal is converted into an analog voltage, allowing a direct replacement of potentiometers.

Electrical Characteristics

Absolute Maximum Ratings (non operating)

Stresses beyond those listed under “Absolute Maximum Ratings“ may cause permanent damage to the device. These are stress

ratings only. Functional operation of the device at these or any other conditions beyond those indicated under “Operating

Conditions” is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
