The POT Click is a Click board™ with the accurate selectable reference voltage output. By employing a high-quality 10mm carbon potentiometer, this Click board™ can provide a very accurate voltage output.
The POT 2 click is also equipped with the SMD jumper, which allows the maximum reference voltage to be selected between two typically used values: 2.048V or 3.3V. The output is buffered with a rail-to-rail buffering operational amplifier. It provides constant input and output impedance. The output current is limited by the protection circuit at the output, preventing damage if the output is shorted to GND.
This Click board™ can be used for development of applications that require voltage reference other than what is commonly available as an output from a dedicated IC.
The applications which can benefit from using the POT click include:
- HMI applications where the potentiometer can be used to provide fine control of the movement of a step motor
- the intensity of a LED segment related applications
- backlight amount of a TFT screen related applications, and
- similar applications that require fine control of the voltage reference
