5.10.2 Definitions

Reference Voltage

The on-chip ADC has a built-in reference, which provides the reference voltages for the ADC.

Analog Inputs

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.

Converter

The on-chip ADC uses a 12-bit four-stage pipeline architecture, which achieves a high sample rate with low power consumption.

Conversion Modes

The conversion can be performed in two different conversion modes:

  • Sequential sampling mode (SMODE = 0)
  • Simultaneous sampling mode (SMODE = 1)
