I have questions for PCM1862's internal PGA.
Would you answer following questions?
1. Would you provide the min/Max data of PGA gain error against configuration step(0.5dB)?(For example, it is 0.5dB+-0.2dB)
2. Is there any issue except output data spatulation when we configure PGA gain as causing saturation?(For example, configure gain as +32dB for 2.1Vrms input)
3.Is there any risk as like as causing damage on device when we change I2S BCLK's frequency without stopping I2S?
4.We expect that we can convert audio input signal to 0dB but we observed distorted audio data at approx -2db under specific condition as below. Would you tell me following behavior is expected?
We configured ch as differential and 15.5dB and input analog audio signal that is smaller than 2.1V. Then, we expect we can observed undistorted signal until 0dB on digital audio output. However. digital audio data have distortion from -2.1dB.
I'm looking forward to hearing back from you.
