I have an issue about AD7768 as below:
I used "SPI control mode" to set wideband or sinc filter mode, and "let pin11 floating".
When the FILTER_TYPE_A is set SINC filter mode, ADC work is normal.
But the FILTER_TYPE_A is set wideband mode, ADC DRDY doesn’t pull-high and DATA doesn’t action.
I want to konw why I cannot use "SPI control mode" to cantrol ADC filter type, thanks.
