8.15 VREF

The shared voltage reference modules (VREF1 and VREF2) in these devices contain a configurable voltage reference buffer which allows users to supply a stable reference to on-board analog peripherals. It also supports bringing in an external reference for applications where higher accuracy is required.

VREF1 features include:

  • 1.4V and 2.5V user-selectable internal references
  • Internal reference supports full speed ADC operation at 1.68Msps
  • Support for comparator operation
  • Support for bringing in an external reference on VREF+/- device pins
  • Requires a decoupling capacitor placed on VREF+/- pins for proper operation. See VREF for more details.

VREF2 features include:

  • 1.4V and 2.5V user-selectable internal references
  • Internal reference supports reduced speed ADC operation at 0.5Msps
  • Does not require a decoupling capacitor placed on VREF+/- pins for proper operation.

For more details, see the VREF chapter of the MSPM0 G-Series 80-MHz Microcontrollers Technical Reference Manual.
