AD1974 data format

I Have a (maybe dumb) question.


I use a adsp-21261 to interface an ad1974. I have configured the adc by spi and it outputs the adc data via the sport interface to the adsp.

The adsp loads the data from the sport interface via DMA into a buffer from where the data is being processed.


This all works fine, but I don't know what the format of the data is. Is this an unsigned integer with a range of 0 to 2^24 which corresponds with a voltage from 0 to Vcc?


Kind regards,
