Anyone know why is it very difficult to find a 8bit with MCU with DAC? If one requires a ADC instead, almost all 8bit incorporated this into the controller...
If you can not find a microcontroller with DAC you still have the following options:
- use PWM pin as DAC. You will need 1 resistor + 1 smoothing capacitor as external components ..
- build DAC as resistor ladder as per attached link: https://www.qsl.net/yo5ofh/pic/tone_generator.htm
Try PSOC from www.cypress.com
You'll discover another point of view to DAC and ADC related.
As IanP said it's much easy to build and DAC based on PulseWidthModulation, and a low pass filter built on simple resistor and capacitor.
An ADC it's not such easy thing, that's why the manufacturer insisted on ADC.
