ABSTRACT:
A segment digital/analogue converter for conversion of an eight-bit PCM-work into an analogue output voltage in accordance with the CCITT A-law, with a weighting network and a stepwise switched operational amplifier, with inputs for connection of each bit of said PCM-word with said weighting network and said amplifier via digital gates and low-impedance switches and with a control line for controlling the sign of said output voltage in accordance with the sign-bit of the PCM-word. The converter is characterized by connection to ground of both ends of the weighting network's resistor chain, by two resistors for the continuous resp. the switched input of each a predetermined current to the output line of the weighting network and by a switchable voltage divider at the output of the stepwise switched amplifier.
