ABSTRACT:
The disclosed high resolution analog to digital converter circuit has an integrator circuit responsive to the unknown analog input. The integrator circuit is operated for a fixed period of time during which, on a periodic basis, a predetermined charge is dumped from the integrator circuit capacitor. A counter is incremented each time a dump occurs and the counter value at the end of the fixed period is related to the high order digits of the digital value for the unknown analog signal. A digital number corresponding to the output level of the integrator is determined by a successive approximation circuit both before and just after the fixed period. The difference between the two values determined by the successive approximation circuit is related to the low order digits of the digital value for the unknown analog signal.
