HZ to V click is a device that can convert input frequency of the signal with virtually any wave shape to a DC voltage output, with a level proportional to the input frequency. It has a linear response, and by applying a signal with the frequency between 10Hz to 10kHz on its input, the Click board™ will generate a DC voltage, ranging from 0V to 3.3V. Hz to V click features very good linearity, covers a wide input frequency range from 10Hz to 10kHz and it has good temperature stability.
