Frequently Asked Questions
How much bandwidth and slew rate does the BUF634P provide?
The BUF634P delivers up to 250MHz full-power bandwidth and a 2000V/µs slew rate, making it suitable for high-speed signal buffering, fast pulse applications, and driving ADC inputs in test and measurement systems.
Can the BUF634P drive capacitive loads directly?
Yes. The BUF634P is specifically designed as a unity-gain buffer to drive heavy capacitive loads without instability. Its low output impedance and high output current (up to 250mA) make it ideal for cable driving and ADC front-end stages.
Which supply voltages are compatible with the BUF634P?
The BUF634P operates on dual supplies from ±5V up to ±15V. This wide supply range offers flexibility across different system architectures, including both 5V and 15V analog power rails.
Which substitutes or alternatives are compatible with the BUF634P?
Close alternatives include the BUF634T (same die, SOT-23-5 SMD package) and the OPA633 (TI, similar wideband buffer). The LMH6321 is another high-current buffer option if higher drive capability is needed.
Is the BUF634P RoHS compliant and available for purchase in small quantities?
Yes, the BUF634P is RoHS compliant and lead-free. It is available for inquiry from $8.93 per unit (qty 34+), with MOQ of 1 and global shipping supported.
