The components required to create a Slope A/D converter include:
• Precision comparator
• 4-bit programmable current source
• 16-channel analog MUX
• 16-bit timer with capture register
This section will discuss using these components for a Slope A/D.
Each analog input channel is multiplexed to a single analog input source to be converted by
means of a slope conversion method (using a single precision comparator). The programmable
current source feeds an external capacitor to generate the ramp voltage used in the conversion.
