The ADC wrapper is modified to incorporate the new timings and also other enhancements to improve the timing control of start of conversions. Figure 4-2 shows the interaction of the analog module with the rest of the F2803x system. 64-Pin VDDA 80-Pin VDDA (3. 3 V) VDDA (Agnd) VSSA VREFLO Interface Reference Diff VREFHI A0 B0 A1 B1 A2 COMP1OUT AIO2 AIO10 10-Bit DAC Comp1 VREFLO VSSA Tied To VSSA VREFLO VREFHI VREFHI Tied To A0 A0 A1 A2 A3 A4 A6 A7 B0 B1 B2 B3 B4 B6 B7 A1 A2 A3 A4 A6 A7 B0 B1 B2 B3 B4 B5 B6 B7 A5 Simultaneous Sampling Channels B2 A3 B3 A4 B4 ADC COMP2OUT AIO4 AIO12 10-Bit DAC Comp2 B5 Temperature Sensor A5 A6 B6 A7 B7 COMP3OUT AIO6 AIO14 10-Bit DAC Comp3 Signal Pinout Figure 4-2.

The sample-and-hold circuits can be sampled simultaneously or sequentially. These, in turn, are fed by a total of up to 16 analog input channels. The converter can be configured to run with an internal bandgap reference to create true-voltage based conversions or with a pair of external voltage references (VREFHI/VREFLO) to create ratiometric-based conversions. Contrary to previous ADC types, this ADC is not sequencer-based. It is easy for the user to create a series of conversions from a single trigger.
