Hi, i'm wondering if it is possible to use an AGC circuit at the input to the AD9629 (or similar ADC), and somehow control the VGA Gain from a feedback signal direct from the ADC?
Does the AD9629 have the ability to output a signal level, based on it's input signal level, which could be used as the control voltage for a VGA in an AGC loop? Or is a separate peak detector or something similar required at the ADC input to measure the input signal level?
Many thanks in advance,
Cheers,
Dave
