Using only a few components and an inte- grated switching circuit it is possible to construct a high-performance voltage- frequency converter. With the component values shown in the diagram, the conversion ratio has a linearity of approx. 1 %. An input voltage from O V ... 1 0 V will produce a corresponding O ... 10 kHz squarewave output voltage. By means of potentiometer P 1, the circuit can be adjusted so that an input voltage of O V will produce an output frequency of O Hz.
