I would like to know about ADS1231,what is its maximum weight it can measure?
this is the sample loadcell I am having www.vetek.com/.../article
Since the ADS1231 does not include a load cell, it does not measure weight directly. Therefore, the maximum weight would be determined by the load cell you choose, not the ADC.
The ADC measures the bridge output voltage. As long as the output voltage is less than the ADC's full-scale range, the ADC can measure that voltage.
You can check out the following link for more details on how to correlate the load cell specifications to ADC parameters: https://training.ti.com/defining-noise-performance-low-speed-delta-sigma-adcs?context=1139747-1140267-1128375-1140017-1140209
