Uses Precision Monolithics DAC-100 CCO3 D/A converter and CMP-01CJ fast precision comparator in combination with Advanced Micro Devices AM2502PC or equivalent successive approximation register to compare analog input with series of trial conversions. Clamp diodes minimize settling time and prevent large inputs from damaging DAC output. Digital output is available in serial nonreturn-to-zero format at data output DO shortly after each positivegoing clock transition.—D.
