VGA with AD8021 ?

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?
