Development Kit Frequency to Voltage Converter for use with A/D Conversion, Capacitance Measurement, Frequency to

HZ to V 2 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 features a specialized IC labeled as VFC32KU, which has a good linear response and temperature stability. By applying a signal with the frequency up to 120kHz on its input, the Click board™ will generate a DC voltage up to 3.3V. The IC is supplied by a dual-voltage boost DC/DC converter IC, which provides the power supply of ±15V, required for the VFC32KU IC operation.
