Analog to digital converter |
摘要 |
In an analog-to-digital converter of a parallel comparison type having a plurality of comparators for comparing an analog input voltage with different reference voltages and converting a comparison result into a digital output by means of an encoder, a plurality of comparators each having a different input dynamic range are used to widen the analog input voltage range up to the power source range of positive and negative voltages.
