25 Successive Approximation Type A/D Converter (SA-ADC)
25.1 General Description
The successive approximation type A-D converter (SA-ADC) has 12 channels with a built-in function supporting
an electrostatic capacity type switch (touch sensor supported) in addition to the normal A/D conversion.
25.1.1 Features
•
Built-in sample/hold 12-bit successive approximation type A-D converter, which enables channel selection
from multiple channels.
•
Supports to start the A/D conversion using the timer.(trigger mode)
•
Touch sensor supported.
25.1.2 Configuration
Figure 25-1 shows the configuration of SA-ADC.
