Hello, how are you?
I have been using ADAU1701 with microcontroller, interfacing using i2c mode at 400Khz.
I would like to know what would be the maximum practical (safe) speed using it in SPI mode? The datasheet doesn't say it. Can I expect 1Mbps or more?
Would it be OK if I don't connect the COUT pin, so the DSP only receives data, but I can't read it back? Then I could get away with only 3 pins of the microcontroller.
Thank you very much!
