Have any audio differential input ADC and DAC parts SNR can reach up to 114 dB?
We have several DACs that can reach that level of SNR but no ADCs. Around 109dB is the best for DNR specification. What is the application and how many channels? Give us more info.
About ADC, customer just need stereo channel, but for DAC request, they need 8-channels at least.
And they also want to support I2S and TDM input format.
We promote ADAU1962(DNR up to 115.5 dB) to customer, but they found ADAU1962 THD+N in worse case (MAX) is -85 dB, and our competitor Cirrus Logic CS42528 THD+N can reach to -100 dB, and MAX is -94:
Have any advise for this?
A quick answer is that our part is automotive qualified which means we have to be more stiringent in our specifications and use the 6-sigma numbers from all the silicon corner cases. The Cirrus part is not automotive qualified so they did not have to specify to the same standards. Rajeev and I will be looking into the characterization data as soon as we can to see what it looked like.
Thank you your reply!
