The name of this analog to digital converter comes from the fact that the integrator output changes linearly over time, with two different slopes during the conversion process. Since it uses the same clock input for both phases of conversion, a drift in the clocking frequency will not affect the accuracy of the output. The Dual Slope is best suited for applications Upload. Another common ADC is the dual-slope converter, which relies on integration.
