ADC Input Voltage Range of MPC5744P-DEVKIT

[ykarata1]

Dear All, I will use MPC5744 DEVKIT and try to read Analog Voltage. In the documents I am confused with ADC input range. In some parts, I have seen 3.3V in some 5.0 V as reference. I need to use 5V input range. If it is 3.3V how can I change input range to 5V. If it is already 5V, It is OK for me. Thanks.

Hi,

MPC5744P supports both 3.3V and 5V voltage reference:

Notice that both VDD_HV_ADRE0 and VDD_HV_ADRE1 need to be supplied by the same voltage source.

If you take closer look at the schematic (https://www.nxp.com/webapp/Download?colCode=SCH-29333-E), you will see:

And:

So, it can be easily configured as needed.
