V to Hz 2 click 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 3.3V on its input, will result in generating the pulse train with frequency linearly proportional to the input voltage. This click features very good linearity, covers a frequency range between 200 Hz to 120 kHz, and it has good temperature stability.
