3.4 Analog Module Differences

This section outlines the analog differences between F280013x, F280015x and F28E12x. One Programmable Gain Amplifier(PGA) is a new addition to the F28E12x and there is now one ADC versus the two ADCs on the F280015x and F280013x devices. Table 3-3 shows the analog module instances differences that can be considered when migrating applications between F280015x, F280013x, and F28E12x. The register differences for analog modules are given in Section 3.4.1.

(1) In porting software from F280013x or F280015x to F28E12x (or the other way around), care must be taken to make sure that the correct ADC channels are used because of a difference in channel assignment, see Section 3.9.
