PDK-DS-MCS11_v020 – Apr. 20, 2018
5-16. Analog-to-Digital Conversion (ADC) module
Fig. 5-16-1 ADC Block Diagram
The MCS11 provides one 10-bit resolution analog-to-digital conversion module with 10 external channels and
one channel for internal 1.20 volt band-gap reference voltage; it allows the conversion of an analog input
signal to a corresponding maximum 10-bit digital number, its block diagram is shown as Fig. 5-16-1. For the
conversion process, analog signal will be sampled and held first, then sending into the converter to generate
the result via successive approximation. The analog reference high voltage of ADC is the positive supply
voltage (VDD) and the reference low is always the GND. Higher than 1uF capacitor is recommended to be
placed between VDD and GND to have better AD conversion result.
