We are using AD7193 in our product for Load Cell measurement. Performance of it is quiet good. Now we are in need of a similar ADC with 16-bit resolution.
16-bit, PGA, SPI, 50Hz rejection, decimate filters, filter word selection, offset correction, DRDY interrupt.
Dual channel is sufficient.
You may take a look at AD7795 or AD7798, both are 16 bits ADC with the above requirements.
