He was asking for a DAC.

    Can anyone recommend a good, easy to interface, 12 bit Dac for the Stamp?
    I'd like to look at both, voltage output and also a 4-20ma output.

    Web Searches pull up numerous results but I was curious to what some of you
    folks have used successfully.

    Thanks,
    Richard

    Good documentation with example code available (from Parallax) that works
    the first time<G>. Nice beast.

    Ack Ack. Dyslexia abounds. Thanks for the correction.

    Richard,
    Perhaps one of these would fit:

    MAX531 / 538 / 539 - Single 12-bit voltage out
    DAC7611 - Single serial 12-bit voltage out
    DAC7612 - Dual serial 12-bit voltage out
    DAC7624 - Quad serial 12-bit voltage out
    or
    DAC 8501 - Single serial 16bit voltage out, Rail-to-Rail (pretty cheap @ ~
    $10)

    Haven't used any of them, hope it helps though.....

    Analog Devices AD421 is a 16 bit DAC with 3 wire SPI interface and 4-20 mA
    output. Also requires an external depletion mode FET (DN25D, ND2020L,
    ND2410L, etc) for its power supply section.

    It can be loop powered if you want to use opto-isolators on the 3 control
    lines. That's how we use it for one of our RTD temperature monitoring systems.
