TMS320F28379D: ADC sensing and DAC output

raja sekhar15

Part Number: TMS320F28379D

I am trying to sense sine signal from adc with +-1.5v and offset 1.5V. The same signal i want to display through DAC by removing 1.5V dc offset which is given for ADC. Can anyone please tell me , why i am not getting that?

Hi Raja,

The DAC can only output a signal from 0v to the reference voltage. If you remove the 1.5v offset from your signal, the DAC will output half cycles of the sine wave from 0v to 1.5v. Is this what you are seeing?

Also, are the screenshots from Simulink?
