Not sure what kind of spec you need but the PIC12F/LF1822/PIC16F/LF1823 line have a 5 bit DAC. You will need to buffer the ouput to really be useful. PWM and a low pass filter offer a low cost alternative.

Hello MadWolf , thanks for the reply ! They have indeed a DAC , but its only 5 bit hmm. I need a µC with more pins( eg 20) SPI, I²C ,DAC and a USB-interface.
I've also seen the PWM with LPF , but its rather slow.
I'll keep on searching , probably I'll use an external DAC with SPI.
