Abstract :
Describes a serial output sign and magnitude successive approximation A/D converter. After deciding sign bit at the first clock pulse the signal is applied in one polarity to an A/D which uses minimum hardware. Off the shelf TTLIC´s have been used. Parallel output can be obtained with minor modifications.
