Voltage - frequency conversion circuit

AD654 voltage-frequency converter is a low cost, they can work at + 5 ~ + 36V single supply, can also work in 5 18V dual supplies a maximum input voltage of 36V, the maximum op
Voltage - frequency conversion circuit - schematic

erating frequency of 500kHz, static current is 2. OmA, typical temperature coefficient of 50 10 -6lcc, typical drift 4vV/C. Voltage-frequency converting circuit as shown 10--40 shows the basic voltage-frequency conversion circuit. pin voltage from the input voltage controlled evacuation amplified voltage controlled oscillator frequency of the oscillator is changed, the signal by the driver circuit from O pin output (for the collector electrode open-circuit output, you need to access the pull-up resistor). Electric four-way output frequency by the input voltage vl, and external connection R, C decided fuu-r yIN/(10RC)
