I am trying to use AD8429 to amplify signals at frequency up to 5-10 MHz.
and I find a large peaking in gain at about 7 MHz. I repeated measurements with different values of the gain resistor R3, and also without the RFI input network.
These results are quite different from the Gain vs. Frequency figure reported in the datasheet (Figure 9 page 8).
By the use of a small (5 pF) capacitor across the gain resistor R3 I can slightly improve the situation.
Do you think that it is possible to stabilize these amps on breadboard? Is there any suggested stabilization scheme?
Thanks in advance
