    Hi,

    I am tryng to save I/O pins of my pic877 controller by using a SPI or i2c DAC. I have search the web which has
    popped up tons of these devices(ie fr maxim, analog, microchip, etc)

    Other than the right technical spec, i like to hear some opinions fr other users which may have been there...

    Thank
    Mcuman(2nd post)

    When comparing converters make sure you look at the accuracy as well
    as the resolution. Also check the accuracy of the reference.

    Analog Devices makes state-of-the-art converters. They can be pricey. Easy
    to get samples and excellent application notes.

    Maxim parts are very good. I would not use any Maxim part that is not stocked
    by Digikey and Mouser. I have had to remove Maxim parts from my designs
    due to availability.
