• Operates on a wide single-supply voltage range from 4.5 V up to 36 V.
• Designed for surface-mount integration using the TO-263 (DDPAK-5) thermal package.

Instrumentation, Op Amps, Buffer Amps Applications

• Video signal distribution and line driving
• High-speed data acquisition system front-ends
• Impedance matching between stages in analog circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance and RoHS status during procurement. Confirm the 'F/500' designation corresponds to the standard tape-and-reel packaging quantity of 500 units. Ensure the TO-263-5 pinout matches the target PCB footprint design requirements before finalizing orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel buffer requires high current drive capabilities exceeding standard op-amp limits. The TO-263 package offers superior thermal dissipation compared to smaller surface-mount options. Consider the 180 MHz bandwidth and 2000 V/µs slew rate for applications demanding rapid signal transitions without significant distortion.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the BUF634 family of high-speed buffer amplifiers originally developed by Burr-Brown and acquired by Texas Instruments. The family includes variants with different packages such as PDIP-8, SOIC-8, and TO-220. The F/500 variant specifically denotes the surface-mount DDPAK-5 form factor supplied in reels.
