I need to amplify signal up to 1MHz sine, amplitude 10uV - 1V from sensor for ADC 16bit.
The decisive factor is the amplitude and phase.
In other words, I need an amplifier with switchable gain 1x,10x,100x,1000x.
Because we did not find a suitable VGA, I would like to try 3x AD8021 and switching using a relay.
It is a good idea or do you recommend another solution?
