Hello everybody, I have just run into this amazing DSP, and would like to ask a couple of question. Could someone please help me?

The idea is, I am going to build a device, which produces pulses of filtered white noise at a frequency about 50Khz, then a couple of microphones catch the reflection, then the reflection is downscaled preserving the time domain by multiplying on a 32Khz sine wave and after all that sent to the output. Could you please tell me, what is the maximum sampling rate of the 1701? The customer support told me, that "If you want to go all the way to 192 kHz and still have very good audio performance and bandwidth, then it might make sense to use one of the following ADAU1701..." So it means, that it may support at least 384Khz, right? The other question is, whether the power of this chip is enough for the task described here?

Thanks again.

The -1701 data sheet says that, "sampling rates of up to 192KHz are supported." So the reference to 192KHz refers to max sampling rate, not the max Nyquist bandwidth which therefore is 192KHz / 2.
