Hello,
I believe there is an error in Figure 13 of the PGA2505 data sheet. The 4.7uF polarised capacitor attached to VA- (pin 17) appears to be connected the wrong way round.
I would be interested to know if my hunch is correct.
Regards.
Tim

Hi Tim,
You are correct. The polarized capacitor at VA-, pin 17, should have the negative end at the VA- pin since VA- is more negative than AGND.
