The on-chip ADC has a built-in reference, which provides the reference voltages for the ADC.
The on-chip ADC consists of 16 analog inputs, which are sampled either one at a time or two channels at a time. These inputs are software-selectable.
The on-chip ADC uses a 12-bit four-stage pipeline architecture, which achieves a high sample rate with low power consumption.
The conversion can be performed in two different conversion modes:
