Hi..Do you know any Pic model that have digital to analog converter?
I can do my process with digital to analog converters but ı must do it using pic because of my homework?
The **broken link removed** has a DAC built in. There are others on MicroChip's site. If you don't want to use a dsPIC you can add a TC1320 to your PIC, use PWM and a LPF, or a R2R ladder as Nigel suggested.
I'm a fan of the PWM followed with a low pass filter followed with a buffer amp followed, if required, by an amp to match the impedance requirements of whatever you are driving.
