Package and mounting
The Maxim MAX4014EUK is a single-channel voltage-feedback buffer with a 200 MHz -3 dB bandwidth and a 600 V/µs slew rate, designed for single-supply operation from 3.15 V to 11 V. The rail-to-rail output stage lets it swing close to the supply rails, which matters when you are driving an ADC or a cable with limited headroom. Quiescent current runs 5.5 mA — not the lowest power, but reasonable for the speed class. The SOT-23-5 package keeps the board footprint small, though the 120 mA output current rating means you are not driving heavy loads directly.
Supply voltage and output swing — the practical limits
The supply span runs from 3.15 V minimum to 11 V maximum. At 3.3 V nominal that leaves only 150 mV of headroom before the buffer drops out of regulation — a 3.0 V rail is too low. On the top end, 11 V lets you use a standard 9 V or 10 V rail without an extra regulator. The rail-to-rail output is a real advantage here: at 3.3 V supply the output can swing within a few tens of millivolts of each rail, preserving dynamic range. Input offset voltage is specified at 4 mV, and input bias current at 5.4 µA — both moderate figures that should not cause issues in most AC-coupled or DC-accurate paths.
Temperature grade and package fit
The SOT-23-5 (SC-74A) is a standard surface-mount footprint, hand-solderable and compatible with automated pick-and-place. Note the RoHS non-compliant status: if your assembly line requires RoHS, you will need to source a lead-free variant or accept the exemption paperwork.
Lifecycle and sourcing posture
No last-time-buy or allocation pressure expected on this established buffer.
