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.
