Functional Description and Application Information
4.19
4.19.1
4.19.1.1
In order to sample the MM912F634 analog die analog sources, a 10-bit resolution successive approximation Analog to Digital
Converter has been implemented. Controlled by the A/D Control Logic (ADC Wrapper), the Analog Digital Converter allows fast
and high precision conversions.
