V to Hz 3 Click Board
Product Code: MIKROE-5250
The V to Hz 3 Click Board? is a compact add-on board that converts an analogue voltage input signal into a specific frequency pulse wave signal. This board features the AD7740, an ultrasmall synchronous voltage-to-frequency converter from Analog Devices. The AD7740 has a linear response, so applying a voltage from 3V up to 5V on its VIN terminal will generate the pulse with a frequency linearly proportional to the input voltage. It contains an integrated 2.5V bandgap reference defining the span of the VFC and can be overdriven using an external reference. The full-scale output frequency is synchronous with the input clock signal provided by the LTC6903 programmable oscillator, with a maximum input frequency of 1MHz. Based on the analogue input value, the output frequency goes from 10% to 90% of the input frequency. This Click board? is the most suitable for low-cost analogue-to-digital conversi
