7.10 Analog Peripherals

The analog subsystem module is described in this section.

The analog modules on this device include the ADC, PGA, temperature sensor, buffered DAC, and CMPSS.

The analog subsystem has the following features:

  • Flexible voltage references
    • The ADCs are referenced to VREFHIx and VREFLOx pins.
      • VREFHIx pin voltage can be driven in externally or can be generated by an internal bandgap voltage reference.
      • The internal voltage reference range can be selected to be 0 V to 3.3 V or 0 V to 2.5 V.
  • The buffered DACs are referenced to VREFHIx and VREFLOx.
    • Alternately, these DACs can be referenced to the VDAC pin and VSSA.
  • The comparator DACs are referenced to VDDA and VSSA.
    • Alternately, these DACs can be referenced to the VDAC pin and VSSA.
  • Flexible pin usage
    • Buffered DAC outputs, comparator subsystem inputs, PGA functions, and digital inputs are multiplexed with ADC inputs
    • Internal connection to VREFLO on all ADCs for offset self-calibration

A. On lower pin-count packages, the input to Gx_ADCC will share a pin with the PGA input. If the PGA input is unused, then the ADCC input can allow the pin to be used as an ADC input, a negative comparator input, or a digital input.
B. AIOs support digital input mode only.
C. The PGA RFILTER path is not available on some device revisions. See the TMS320F28004x Real-Time MCUs Silicon Errata for more information.

VDACOptional external reference voltage for on-chip DACs. There is a 100-pF capacitor to VSSA on this pin whether used for ADC input or DAC reference which cannot be disabled. If this pin is used as a reference for the on-chip DACs, place at least a 1-µF capacitor on this pin.
