Abstract:
A digital to analog converter for converting a digital signal to an analog signal, comprising:decoder logic configured to (i) decode said digital signal to generate a plurality of control signals, and (ii) generate a first range of control signals; a plurality of analog signal sources responsive to said control signals; and a plurality of flip-flops configured to interface signals to the analog signal sources, wherein said plurality of flip-flops are operable in: a first mode in which the flip flops are configured to receive said control signals from said decoding logic to interface said control signals to said plurality of analog signal sources; and a second mode in which respective ones of said flip-flops are coupled in at least one serially shiftable scan chain, to permit at least a majority of said analog signal sources to be individually addressable by inputting control signals via said scan chain.
