The 250 mA output per channel means this isn't a signal-level part — it's meant to push video lines, drive ADC inputs through long traces, or buffer a reference into a heavy load. ## Package and mounting A 3750V/µs slew rate means this buffer can swing a 10 V step in under 3 ns. That's the spec that tells you it's a high-speed part, not a general-purpose amplifier. For the repair bench or the design desk, the practical consequence is clean pulse response into loads that would slew-limit a 20 V/µs part into a triangle wave. The 210 MHz bandwidth supports video rates, fast pulse trains, and ADC front-end settling where the buffer's own rise time doesn't become the bottleneck. The input bias current of 250 nA is not the ultra-low figure you'd want for a precision integrator, but that's not the job here — this is a current buffer, not a preamp. ## Package and footprint for the board The BUF634AIDRBR comes in an 8-VDFN exposed-pad package, with the supplier device package listed as 8-SON (3x3). That 3 mm × 3 mm footprint is compact enough for dense layouts, and the exposed pad under the part is the primary thermal path — the 250 mA output current can dissipate several hundred milliwatts, so the PCB needs a via-stitched thermal land under the pad. Surface-mount only; no through-hole variant in this order code.","metaTitle":"BUF634AIDRBR High-Speed Buffer, 3750V/µs Slew Rate","metaDescription":"Texas Instruments BUF634AIDRBR general-purpose buffer op-amp: 3750V/µs slew rate, 210 MHz bandwidth, 250 mA output, -40°C to 125°C.
