Hey everyone!
So I am planning to use a PCM5242 DAC chip from TI, in conjunction with a ADI ADAU1452 DSP board from midiworx for my project. However, I would like to set the DAC chip to hardware mode since I would be doing all of the processing on the ADI DSP chip, and would prefer not to use a microcontroller for simplicity, Has anyone tried to connect these 2 chips together in hardware mode before?

I heard from online that the PCM5242 is similar to the PCM5102 in operation, and also how the PCM5242 is similar to the PCM5122 in terms of register operation. So another question is, if i wrote a program that worked with pcm5102, will it work with the PCM5242?
Yes, PCM5102, PCM5122 and PCM5242 are the same in terms of hardware operation mode. PCM5102 can work in HW (standalone) mode only and does not have any regulation opportunity. PCM5122 is PCM5102 plus some register set allowing volume control, master/slave tuning and so on. PCM5242 / PCM5142 is PCM5122 plus DSP.
And yes, they all will work in HW mode with ADAU1452 in the same manner.

That’s great to hear! Another concern I have is with zero data detection. So if there is nothing playing on the dsp, would the DACs mute and make a loud pop on the out?
