Hello,

 

I read the following application note about ADV7842.
  Gain Settings in the ADV7844/ADV7842("Gain Setting in the ADV7844_ADV7842.pdf")

I have two questions about PGA(Programmable Gain Amplifier) of AFE in ADV7842.

 

Q1.
Is gain of PGA fixed by the maximum value of 1.4 ?

 

Q2.
Can I change a gain value of PGA ?

If yes, please teach a way.

 

Best regards.
