Poking around for a few hours on the TI site and haven't got a good feel for the right part... I have been using the ADS123x and ADS124x product in digital weight indicators. The sensor is the common wheatstone bridge load cell. These products have an update rate of 30-60/sec and the ADS1232 itself only has a sample rate of 80sps. My application needs at least 1000 samples/sec and to still maintain at least 17-bits (preferably 18) of the 24-bit resolution. Can anybody suggest something similar to the ADS1232 but faster?
Thank you,
Chris
Hi Chris,
Take a look at the ADS1250:
http://www.ti.com/product/ads1250
Effective resolution is 18+bits for data rates from 10SPS to ~30kSPS, across all 4 PGA gain options (1,2,4,8).
Let me know what you think.
Best Regards,
Marc
Thanks Marc. I'm not sure how I missed the ADS125x line. It looks good and I will definitely check it out.
Thanks again,
