JAJSH51C August 2000 – March 2024 BUF634
PRODUCTION DATA
The excellent bandwidth and fast slew rate of the BUF634 device are useful in a variety of high frequency open-loop applications. When operated open-loop, printed-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-µF ceramic chip capacitors at the device pins in parallel with solid tantalum 10-µF capacitors. Source resistance affects high-frequency peaking, step-response overshoot and ringing. Best response is usually achieved with a series input resistor of 25 Ω to 200 Ω, depending on the signal source. Response with some loads (especially capacitive) can be improved with a resistor of 10 Ω to 150 Ω in series with the output.
