HIGH SPEED ANALOG-TO-DIGITAL CONVERTER
(TYPICAL INPUT DEVICE)
An analog-to-digital converter with a resolution of 8 bits and a conversion
time of 2 microseconds may be connected to the Real-Time Option. The
input-output transfer instructions, series 11, for the converter are:
sci - 701115 - Sample the analog input. Convert the sampled quantity to
digital form and load the AC with the converted number.
701101 - This micro-instruction starts the converter. In a period of 2
microseconds the converter will form an 8-bit number pro-
portional to the analog input.
701104 - C(A-D converter) V C(AC) => A(AC).
