High-speed quad op-amp for video and ADC drive
The Maxim Integrated MAX4384EUP is a quad voltage-feedback operational amplifier packing 210 MHz of -3 dB bandwidth and a 485 V/µs slew rate into a compact 20-TSSOP package. Each of the four channels delivers rail-to-rail output swing while drawing 7.5 mA per amplifier from a supply span of 4.5 V to 11 V — comfortable on a single 5 V rail or split ±5 V supplies. The 75 mA output drive per channel and 8.5 µA input bias current suit it for driving multiple video loads, high-speed ADC inputs, or cable buffers in industrial imaging and test equipment.
Package and mounting
At 485 V/µs, this part slews fast enough to reproduce a 5 Vpp 50 MHz sine wave without visible slew-induced distortion. For a video DAC reconstruction filter or a CCD sensor output buffer, that slew margin means the amplifier isn't the bottleneck — the external passive network and the PCB parasitics will limit the signal path first. The 210 MHz bandwidth supports closed-loop gains up to about 10 before the gain-bandwidth product starts eating into the flat passband. If you're driving a 75 Ω back-terminated cable, the 75 mA output current per channel handles the load without droop.
Supply rails and single-supply operation
The 4.5 V to 11 V supply span means the MAX4384EUP runs on a single 5 V rail common in mixed-signal systems, or on ±5 V for legacy analog backplanes. Rail-to-rail output swing gives you the full voltage range into a high-impedance load — useful when the ADC reference is close to the supply rail. Input common-mode range isn't rail-to-rail, so for a unity-gain buffer at 0 V input on a single 5 V supply, check the input voltage range against the datasheet's common-mode limits. For AC-coupled paths this rarely matters; for DC-coupled low-level signals it's the one spec to verify before layout.
Package and footprint for the rework bench
The 20-TSSOP (4.40 mm body width, 0.65 mm pitch) is a standard fine-pitch SOIC footprint. Hot-air rework at 350°C with a small nozzle lifts it cleanly — no underfill to fight. MSL level isn't in the record, but for a 20-TSSOP assume MSL 1 or 2; if the reel's moisture-barrier bag has been open past the floor-life window, a 48-hour bake at 125°C before reflow is cheap insurance.
