I'm a Student of ee in fifth Semester and ordered a ads1211 for a project.
But definately I underestimated the complexity of this IC!
I tried a lot to get it working, asked questions on the board and so on. It's like magic, sometime I get answer on the SPI bus like "0x02" or "0x08" and then I power off and on again and nothing there....
But now it's getting a bit frustrating because I would like to work on the whole project and not only on the ADC all the time.
So perhaps there is a easier to use TI ADC out there with specs like this:
- At least 16 bit
- DIP socket
- should have at least 1 ksample/sec
. SPI Interface
- Internal clock would be nice!
What do you think of ADS7813 for my needs?
Thank you for your help and perhaps in the future I will get the ADs1211 working :D
You really haven't said much about what type of sensor you are using. I'm guessing you want to have a DIP device for easier prototyping. That really limits your choices. The ADS1211 is a difficult device to get started with, and the ADS7813 should be easier, however they are both very different devices. It may be a better choice to pick the type of converter that best matches the measurement you are trying to make and see if you can find a surface mount adapter to a SIP or DIP.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
