The Peak/RMS limiter in ADAU1702 is supposed to have a Peak Hold, according to the documentation, but it does not:
Does the RMSTC field do the same thing as a peak hold? It can be changed between ms and dB/s, so I'm not sure what dB/s means for a hold.
Also, is there a way to see what the peak limiter component is doing? If I turn the 3 RMS values to maximum, it should essentially disable the RMS component and leave only the peak component working, right? But if I do this it just behaves like an RMS limiter with the values maxed out.
