A/D Converter
The SAB 80C517 contains an 8-bit A/D Converter with 12 multiplexed input channels which
uses the successive approximation method. It takes 7 machine cycles to sample an analog
signal (during this sample time the input signal should be held constant); the total conversion
time (including sample time) is 13 machine cycles (13
s at 12 MHz oscillator frequency).
Conversion can be programmed to be single or continuous; at the end of a conversion an
interrupt can be generated.
A unique feature is the capability of internal reference voltage programming. The internal
reference voltages VIntAREF and VIntAGND for the A/D converter are both programmable to one
of 16 steps with respect to the external reference voltages. This feature permits a conversion
with a smaller internal reference voltage range to gain a higher resolution. In addition, the
internal reference voltages can easily be adapted by software to the desired analog input
voltage range (see table 2).
