ADC08831 question

Will this ADC08831 chip work with the OBEX code for the ADC0831? It looks to be the same, just smaller and better. I don't want to order a bunch and have an issue....

    Looking at the datasheets between the two, starting with page #9 of both specifically , they both appear to be comparable as far as the way that they communicate. Can you order one or two to double check, just to make sure that they will work in your project?

    Right now, I am starting with low quantities for development just in case it does not work, and I have a few to spare if I burn one up or lose them on my bench :p.... It happens a lot in my work area. I will order 5 or 10 to start off with. Since I am going all surface mount, I would have to change the pad on the circuit board to accommodate for the larger 0831 version. I don't have a lot of room, and I need to keep space down to a minimum per component. That is why I wanted to go with the SOIC-8 instead of the 14.

    The 08831 data sheet does say it is a pin compatible replacement for the 0831 and the communication protocol looks to be the same so it should work with the 0831 driver.
