U/f converter

U/f converter
The present circuit combines simplicity and linearity: it is highly suitable for use as an A-D converter (ADe) far a microprocessor. It consists of integrator IC1, and rnanostable IC2a. Tbe design is such that each triggering of the monostable causes the integrator to be discharged. The amount of charge is proportional to the input voltage. The Irequency at wh ich a11this happens is a rneasure of the input voltage.
