Thermal Accuracy
The MLX90333 features a contactless position

The processed position information is ultimately
reported as a ratiometric analog output or as
PWM (Pulse-Width Modulation) signal. In case of

3DJoystic mode, the device features 2
independent outputs. A 3-pin SPI (serial interface)
mode is also available to transfer the position
