Specifications

5.10 Analog Peripherals

The analog subsystem module is described in this section.

The analog modules on this device include the ADC, 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 must be driven in externally.

•

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 and comparator subsystem functions multiplexed with ADC inputs

•

Internal connection to VREFLO on all ADCs for offset self-calibration
