3.4 Analog Module Differences

This section outlines the analog differences between F28003x and F28002x. The GPDAC is not present on the F28002x and the analog mux table is remapped.

Table 3-3 Analog Module Differences
Module Category F28002x F28003x Notes
ADC(1) Number 2 - ADCA, ADCC 3 - ADCA, ADCB, ADCC
Max Speed 50 MHz 60 MHz
GPDAC Number - 2 - GPDACA, GPDACB
CMPSS(1) Number 4 - CMPSS1 to CMPSS4
Registers CTRIPxFILCLKCTL.CLKPRESCALE[9..0] CTRIPxFILCLKCTL.CLKPRESCALE[15..0] CMPSS filter prescaling size increased on F28003x
Other CMPx_HP has 5 mux input options CMPx_HP has 6 mux input options
Temp Sensor Number 1 - (in ADCC ch 12)
  1. In porting software from F28002x to F28003x (or the other way around), care must be taken to ensure that the correct ADC channels are used because of a difference in channel assignment, see Section 3.9.
