Dear Sir,
May I ask what is advantage or disadvantage to use the digital domain? I probably do not understand how the digital amp (x2 oe x4) works with analog PGA (x32).
If gain 64 and 128 will loose linearity of performance from below gain 32, I would like to know to avoid to use. I read electrical specification and found only gain error and analog supply current have a boundary difference at below gain 32 and above gain 64.
Best regards,
Masa
