I want to control and change a voltage signal within a very low noise level so that I can use a 12 bits ADC to convert that voltage signal. Can use hmc539a to achieve that goal?
If so, what changes should I make compared with the reference circuit from the datasheet?
And I am confused about the function of PIN ACG1 - ACG5?
Note that the whole circuit should be DC coupled and the bandwidth should be better than 1MHz.
