Ask for your helping.
Can we configure the AD7768-1 as an ADC with an adjustable sampling frequency?
Can we directly switch the sampling frequency of the chip through the program? I mean don't change the external hardware device. Simply use the FPGA to input a command to the ADC via SPI .Because I see that the AD7768-1 provides three power modes and kinds of modulator and filters.
There are 4 MCLK divide options that can be set via SPI which will directly change the sampling rate. The question is, do you want to change the sampling rate or the output data rate? The AD7768-1…
Thank you very much for your answer！
There is another question I hope to get your help.
When we operat AD7768-1,if it works in the low power mode and using the sinc5 filter in the default?
And how can I find out the default state after the chip is powered on in the datasheet?
