ABSTRACT:
A method and circuitry are provided for current input analog to digital conversion. A current input (14) is conducted through an input path. The current input is directed through a plurality of current paths (30a-d). A current through each current path (30a-d) is compared against an associated reference current (36a-d), and a respective output signal (34a-d) indicative thereof is output, such that the respective output signals (34a-d) are indicative of a magnitude of the current input (14).
