ABSTRACT:
A system on an integrated circuit chip for providing a digital-to-analog conversion includes a plurality of output members each providing a particular current when energized. These members may be disposed on the chip in a pair of spaced columns. First control lines in the space between the columns of output members provide a thermometer code. Second control lines in this space provide a binary code. The first and second control lines are preferably parallel to the columns. When a first one of the first control lines is energized, different ones or combinations of the second control lines provide progressive values in the output members between "0" and "15", assuming four (4) of the second control lines. Similarly, when a second one of the first control lines is additionally energized, different ones or combinations of the second control lines provide progressive values between "16" and "31" in associated output members. At the same time, the output members providing a value of "15" continue to be energized. Similarly, the energizing of successive ones of the first control lines provides for the generation of analog values within progressive ranges. The output members associated with each of the first control lines are interspersed in the columns in accordance with the analog values represented by these output members to provide a first centroidal arrangement. The output members associated with each of the first control lines are also interspersed with the output members associated with the others of the first control lines to provide a second centroidal arrangement.
