Other Parts Discussed in Thread: TMS320F2811

Hi, I want to ask a simple question, the datasheet regarding ADC module of TMS320F2811, it say that the data is 4095 if input is >3V. So I want to ask if I can input 3.3V voltage. My ADC low referece is 0... TKS~ Kent

    Surely you can, and you will get the ADC result equals to 4095 always as long as the input is larger than 3V.

    However, it does not mean you can input any voltages, since the analog input has a max restriction of 4.6V (see datasheet 6.1 Absolute Maximum Ratings table), otherwise the analog module (or even the whole device) would be damaged.
