DAC
« on: April 14, 2016, 03:22:32 pm »
I would like to create a 16 bit DAC in STM32F103RET6. ButSTM32F103RET6 only has 12 bit DAC. How do I implement a higher resolution DAC in STM32F103RET6?
Thank you. Please see link below

If it's for a DC or a very low frequency applications (e.g. a low speed control loop) then you can use a timer interrupt to dither the DAC output, and low pass filter the result.
