A/D CONVERTER
The
μ
PD17207 has an 8-bit successive approximation A/D converter.
This A/D converter can be used in the following two modes.
Mode
Description
A/D conversion mode
Converts analog voltage input to one pin into digital signal
Compare mode
Compares analog voltages input to two pins
9.1 CONFIGURATION OF A/D CONVERTER
The 8-bit A/D converter consists of a selector that selects an input pin, analog switch, control circuit, 8-bit resistor
string D/A converter, and comparator.
