HIGH SPEED JFET INPUT INSTRUMENTATION
AMPLIFIER
Figure 60 shows an example of a high speed instrumentation
amplifier with high input impedance using the

For G = +1, it is recommended that the feedback resistors for
the two preamps be set to a low value (for instance 50 for 50
source impedance). The bandwidth for G = +1 will be 50
MHz. For higher gains, the bandwidth will be set by the preamp,

Common-mode rejection of the inamp will be primarily
determined by the match of the resistor ratios R1:R2 to R3:R4. It

The summing junction impedance for the preamps is equal to

VIDEO BUFFER
The output current capability and speed of the AD8065 make it
useful as a video buffer, shown in Figure 61.
The G = +2 configuration compensates for the voltage division
of the signal due to the signal termination. This buffer
maintains 0.1 dB flatness for signals up to 7 MHz, from low
amplitudes up to 2 V p-p (Figure 7). Differential gain and phase
have been measured to be 0.02% and 0.028° at ±5 V supplies.
