12.1 Introduction
The 12-bit ADC is a successive approximation analog-to-digital converter. It has up to 19
multiplexed channels allowing it to measure signals from 16 external and 3 internal sources.
A/D conversion of the various channels can be performed in single, continuous, scan or
discontinuous mode. The result of the ADC is stored in a left-aligned or right-aligned 16-bit
data register.
The analog watchdog feature allows the application to detect if the input voltage goes
outside the user-defined higher or lower thresholds.
An efficient low power mode is implemented to allow very low consumption at low frequency.
