The POT Click Board™ is based on a potentiometer with the accurate selectable reference voltage output. By employing a high-quality 10mm carbon potentiometer, this Click Board™ can provide very accurate voltage output. POT 2 Click Board™ 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, which 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.
