The output stage is set for a gain of 10; therefore, the AD8067
has an effective gain of 10, thereby allowing it to maintain a
bandwidth in excess of 55 MHz.
The circuit can be tailored for different gain values; keeping the
ratios roughly the same ensures that the bandwidth integrity is
maintained. Depending on the board layout, Capacitor C5 can
be required to reduce ringing on the output. The gain bandwidth
and pulse responses are shown in Figure 58, Figure 59, and
Layout of this circuit requires attention to the routing and
length of the feedback path. It should be kept as short as
possible to minimize stray capacitance.
