In a dual slope analog-to-digital converter, the conversion cycle is divided into three states; a first state in which the system is initialized by discharging an integration capacitor, a second state in which integration is performed with an analog voltage representing the measured parameter and a third state in which integration is performed with an analog reference voltage representing the full scale of the measured parameter. The duration of each state, derived from a counter, is selected according to the particular application in which the analog-to-digital converter is utilized. In one embodiment, each count is representative of a unit of the parameter being measured or a fraction thereof. The count or value which represents the commencement of the third state has a selected relationship to the minimum value of the measured parameter best suited for the particular application. The number of counts in the second state is selected to be equal to or a multiple of the desired full scale range of the parameter to be measured.
