What is an application delivery controller (adc)? Dual Slope Function • The Dual Slope ADC functions in this manner: – When an analog value is applied the capacitor begins to charge in a linear manner and the oscillator passes to the counter. 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. However in recent years, a new species of ADCs has appeared, and since then attracted lots of attention. It has greater noise immunity compare to other ADC types. Converter.
