Data Sheet
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.
5 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.
