    Question 10-Bit D to A Converter

    Hello everyone - I am trying to find a 10-bit d/a (not a/d) converter that works with I2C and is PDIP (not surface mount). Does anyone have any suggestions? I want to output up to 10 VDC.

    Thanks! Atom058

    You can even use 10 i/o and a R2R network?

    Maxim, Analog device, Texas instruments may do... not smd... harder to find in 2006. I'll try to find something.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Yeah, I have looked at Maxim and TI, but nothing in PDIP greater than 8 bits. - Atom058

    Atom058, As far as the 10 volt output, I would just run the output of a 5 volt DAC thru an amplifier with a gain of 2. As far as the DAC, I have used the LTC-1448 with great success. It comes in an SO8 and a PDIP package. Also it is 12 bits and has Dual Dac's in 8 pins . LOL

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    Hello All - Thanks for all the info. However, I did not see anything that was I2C. I will go to SPI if I have to but I'd rather not - I am going to have 3 of these on a single PIC (F876) and I2C will take up less pins.

    Default Plan B

    Well, it appears that there is no such beast as a 10-bit, I2C, Dip, D/A converter - I have searched hi and low. I have therefore decided to go the SPI route. I have found a 10-bit, 4 channel, SPI in a DIP package that should work fine for me. It is the MAX5250. Thanks anyway!
