Hi: 

I want to use PGA900 for load cell.

Can I use DAC loop back to calibrate output of PGA900 ?

Is it possible? Could it be very accurate ?

    Hello,

    Yes, you can use the loopback feature to calibrate the DAC output of the PGA900 if you wish. The details of the loopback operation are found in the DAC Diagnostics section of the PGA900 datasheet.The accuracy of the measurement is just limited by the 24 bit resolution of the ADC.
