Hi LinceChacko ,
Would you be interested in using our newer ADCs? Like the AD4195-4 or AD4190-4 for your load cell application. It is a highly integrated, multichannel ADC with flexible features and is suitable also for load cell application. Our newer parts ensure longevity compared to our old parts.
For load cell application, I would recommend to use a ratiometric configuration. In a ratiometric configuration, the ADC reference and the excitation of the load cell are derived from the same source. If the excitation source changes magnitude, the load cell output and the ADC reference scale by a similar amount, so the variation in the excitation source does not impact the accuracy of the measurement.
You may use this circuit note, CN0119, as a reference in designing your system.
Regards,
JC
