ABSTRACT:
A digital-analog converter electrically effecting sequential switching between a reference voltage point and each of the connection points formed in a circuit network composed of serially connected impedance elements for taking out desired analog quantity such as signal voltage level, impedance value or the like in response to the application of control pulses, which comprises in combination memory circuits such as R-S flip-flops, gate circuits such as NAND gates and delay circuit such as integration circuits, capacitors and the likes. The provision of the delay circuits, in particular, advantageously facilitates the setting for the initial operation state and the preparation for the sequential switching.
