• RE: PGA2505: Why is the voltage here 0.6V? Shouldn't it be 0V? Is it because of bias voltage? But isn't the bias voltage of chip PGA2505 ± 0.08mV?

  Hello, Both inputs of the PGA2505 are biased at a DC voltage of 0.65V below the VCOMIN voltage on pin 22. If VCOMIN = DGND, both the inputs should be at -0.65V below the DGND on the schematic above. Please see a partial schematic of the recommended…
