When selecting components, the common-mode input capacitance must be taken into consideration. Filter cutoff frequencies can be increased beyond 1 MHz using the AD8033/AD8034 but limited open-loop gain and input impedance begin to interfere with the higher Q stages. This ...

AD8033/AD8034 The output noise over frequency of the preamp is shown in Figure 63. The pole in the loop transmission translates to a zero in the noise gain of the amplifier, leading to an amplification of the input voltage noise ...
