Digital-to-Analog Converter Abstract of the Disclosure A digital-to-analog converter is for use as an interpolative decoder for decoding a linear PCM signal. An output signal of a binary rate multiplier which develops signals of several less-significant bits of the linear PCM signal onto a time axis is directly applied to a driver circuit, by which the segment of a ladder resistance network corresponding to the least significant bit is driven. The ladder resistance network has segments corresponding to signals of several more-significant bits of the linear PCM signal. The effect is to eliminate the need for an adder for the digital addition between the output signal of the binary rate multiplier and the signals of the several more- significant bits.
