Active production, 500V/µs slew rate — the BOM-fit decision
The MAX4392EUA+: Its headline spec is a 500V/µs slew rate paired with 85 MHz -3dB bandwidth — the slew rate is the practical ceiling for large-signal pulse fidelity. For a video or high-speed DAC buffer driving a 50-ohm back-terminated line, the 500V/µs figure means a 5 V step settles in about 10 ns, limited by the output stage current, not the gain-bandwidth product.
Rail-to-rail output and supply flexibility
Each channel delivers 95 mA of output current, enough to drive a 75-ohm video load or a 50-ohm test-point buffer directly. Quiescent draw is 6 mA per device (both channels active), which keeps the thermal rise in the 8-uMAX package manageable even in a still-air environment.
The MAX4392EUA+ ships in a tube (standard MSOP-8), surface-mount. The 8-uMAX/uSOP package has an exposed paddle on the bottom — the datasheet recommends soldering this paddle to a PCB copper land for thermal relief, though the part's 6 mA quiescent plus 95 mA output into moderate loads keeps junction rise low enough that a simple via-stitched pad works. No special bake required for MSL-1 parts; check the moisture-sensitive level on the reel label if the tube has been open.
