I am using the AD7763 in a two daisy-chain configuration with SPI interface.
By checking the status register value returned by the ADC, when appling a waveshape to the input I can see packet coming with not valid data (DVALID = 0). OVR is not set though.
It is not affected by the Decimation (using X64 decimation, but even with X16 shows the same), nor by the LowPower setup. No filters have been activated.
Why is that happening?
