D=A converter system - has transistor circuits for each binary signal value, connected in series with each other

摘要

The converter system has several inputs to which individually allocated binary signals with different values are applied. Its output delivers a corresponding analogue signal. Its own transistor circuit with an inverting and a non-inverting input is provided for each signal value. Their transfer factor between each input and a common output has an absolute value of 0.5. the inverting input of each transistor circuit represents the convertor input for the corresponding signal value. Individual, similarly built transistor circuits are so connected in series with each other by their non-inverting inputs and outputs, that each transistor circuit is directly followed by a circuit to which the nest higher signal value is allocated. The last transistor circuit output is the convertor output.
