    hello

    I'm searching for a microcontroller with analog output. I use in the moment ST72521, but this device has only lots of analog input (or???).

    Have ST any microcontroller with analog outputs?

    Has anybody an idea to build an analog output with other components?

    Thanks for answer,

    It depends on what precision you require for the analog output, a cheap method is to use a timer/pwm timer and an external rc network.

    The other solution is to look at da convertors, try maxim.

    Thanks, Spen!

    can anybody give me an wiring diagram with a example of an rc network? So I can imagine how I build this solution.

    regards

    There is one complete application note available for this i.e. AN1041 (using ST7 PWM Signal to Generate Analog Output (Sinusoïd) ).

    It is downloadable from this same site.
