The V to HZ Click Board™ is a device that converts an analogue voltage input signal into a pulse wave signal of a certain frequency. It has a linear response, so applying a voltage in a range of 0 to 5V on its input, will result in generating the pulse train with frequency linearly proportional to the input voltage.
The V to HZ Click Board™ features very good linearity, covers a frequency range from 10Hz to 10 kHz and it has good temperature stability.
