Sample and Hold IC

Sample and Hold IC: Sample and Hold IC – For accurate analog to digital conversion the analog input voltage should be held constant during the conversion cycle. If the analog input voltage changes by more than ± 1/2 LSB an error can occur in the digital output code. To illustrate the effect of a changing […]
