Abstract

1336526 Digital to analogue converters NEDERLANDSE OPTIEK - EN INSTRUMENTENFABRIEK DR C E BLEEKER 9 May 1972 [11 May 1971] 21598/72 Heading G4H [Also in Division H2] An adjustable voltage is provided by selectively connecting current sources ordered according to the progression I, I.10<SP>-2</SP> ... I.10<SP>-2n</SP> to resistances of a plurality of groups of resistances, all resistances being connected in series and all resistances of a group being of equal value but different to that of other groups. In the Figure two groups of nine resistances of value R and IOR are selectively connected by switches not shown, to bus-bars 23, 24 and 25, 26 to which current sources I and I/100 are connected respectively. The desired voltage appears at terminals 27, 28.
