Abstract
A monolithic light-to-digital signal converter (1.10) includes a photodiode array (1.24) having a plurality of sections with each section producing a current signal in response to incident light, a current-to-digital signal converter circuit (1.28) for converting selected ones of the current signals to a digital signal, and a control circuit (1.26) for scaling the digital signal in response to user supplied programming signals. The control circuit (1.26) also responds to user supplied programming signals to supply control signals to current-to-digital signal converter circuit (1.28). Current-to-digital signal converter circuit (1.28) is responsive to the control signals for combining selected ones of the current signals into a composite current signal and converting the composite current signal to a digital signal.
