Hi Vengadesh,
The ADS1234 is a 4 channel version of the ADS1232. All information currently available with respect to the ADS1232 is on the ftp site:
ftp://ftp.ti.com/pub/data_acquisition/ADS123xREF/ADS123x_CDROM/
I'm currently working on some better example code that will work with this part family and hope to get it posted in the next couple of weeks. I also suspect that there is some other additional information that I might be able to help with depending on the customer's specific application. You can 'start a conversation' with me by clicking on my name on the E2E forum, or you can post specific questions my way completely off the forum by sending an email to:
Best regards,
Bob B
