TMS320F28335: TMS320F28335 DAC example

Muhammad Arsalan Athar

Part Number: TMS320F28335

Dear TI members,

Could you please suggest any example for the DAC implementation on F28335?

I want to take the pulse signal in terms of duty cycle(digital value) as input and then generate an analog values on the watch monitor (0-3V) or at the output of any GPIO.

Thanks

Kind Regards

There is no on-chip DAC on this device. You would need to use an external DAC and update that using a communication bus like SPI. Another option would be to implement some type of PWM-DAC through which you would pass a PWM signal through an RC filter to get an analog voltage output.
