MONOLYTISCH GEINTEGREERDE SCHAKELING VOOR HET OMZETTEN VAN EEN BINAIR GECODEERD SIGNAAL IN EEN GETRAPT ANALOOG SIGNAAL.

摘要

A binary to analog converter circuit, e.g. for a musical instrument, is integrated in I<2>L form and comprises an array of switching transistor units (T1, T2, T3), each transistor unit comprising a plurality of separate I<2>L transistors (T11, T21, T22, T31, T32, T33, T34) the number of which corresponds to its rank of the transistor unit in the array. The output of the switching transistor units is fed to a common sum line (L1).
