HIGH FREQUENCY APPLICATIONS
The BUF634’s excellent bandwidth and fast slew rate make it
useful in a variety of high frequency open-loop applications.
When operated open-loop, circuit board layout and bypassing
technique can affect dynamic performance.
For best results, use a ground plane type circuit board layout
and bypass the power supplies with 0.1
μ
F ceramic chip
capacitors at the device pins in parallel with solid tantalum
10
μ
F capacitors. Source resistance will affect high-frequency
peaking and step response overshoot and ringing. Best
response is usually achieved with a series input resistor of
25
to 200
, depending on the signal source. Response
with some loads (especially capacitive) can be improved
with a resistor of 10
to 150
in series with the output.
