Abstract
An autoranging analog to digital conversion system is provided. The system may include a digitally programmable preamplifier for amplifying a difference between an analog input and an estimate of the analog input. The preamplifier may be coupled to an analog to digital converter for converting the preamplifier output to a digital signal. The system may also include digital domain predictor or estimation logic for determining an optimum gain and analog input estimate for a given analog input. Multiple signal input channels may be coupled to the analog to digital conversion system. The autoranging estimations may be performed on a sample by sample basis or a channel by channel basis.
