A PGA works in analogic field even if there's a digital control of the ampl=
ification. It's usually a resistor ladder connected to an operation amplifi=
er.=0D
The use of a PGA usually add a bit of noise to the system simply because t=
here's another amplification/attenuation even if it's a low noise. This is =
the reason why the codecs with out PGA have always an higher SNR if compare=
d to the one with simple nude ADC but PGA is always necessary in a recordin=
g system. The fact that PGA is integrated or not to the ADC is not strictly=
correlated to the overall quality of the system, usually shorter the dista=
nce between the analogic stage and the ADC better is the quality.=0D

Can you do all the configuration stuff via WiFi, or can you only control r=

It sounds like by "programmable", they mean it can be manual, auto, or man=
ual via WiFi. Unless they give you some control over how auto works.=0D
