    And with the 800 you also get another channel. ULN2003 has 7 and the ULN2803has 8.

    Check the spec sheet. All that information is there. That is why they publish specifications.

    Marko,
    The biggest difference is tha additional channel and the diode to protect from a spike. The data sheets do point out exactly what the diff is, but they are essentially both Darlington arrays ganged together in a Dip chip.

    A 2803 is eight darlingtons with common emiters and is dip8.
    A 2003 is 16 bit 2x8x interpolating Dual channel DAC with intergrated PLL. It says here,:D
    Oh and is a Dip16.

    These were taken from the data sheets via Farnells links.
    If you'r that good at making things easy, take a look at my threads, Just a Quickie & Design problems, I'm getting no where with them.
