The MAX4380EXT-T is a single-channel voltage-feedback op amp from Maxim Integrated, built for applications that need wide bandwidth and fast slew rate in a tiny SC-70-6 footprint. The -3 dB bandwidth of 210 MHz and a 485 V/µs slew rate mean this part can handle high-speed video signals, drive the input of a fast ADC, or condition pulses in a test head without rounding off the edges. Rail-to-rail output lets you swing close to the supply rails on a single 4.5 V to 11 V supply, which matters when you are trying to maximize dynamic range without a negative rail. Input bias current runs 8.5 µA and input offset is 3 mV — typical numbers for a high-speed voltage-feedback stage, not an instrumentation-grade amplifier.
The single 7.5 mA supply current is modest for a 210 MHz part, so it stays cool enough in a densely populated board.
Active lifecycle, RoHS note
One catch: it is listed as RoHS non-compliant. If your BOM requires RoHS-10 exemption-free compliance, you will need to check the latest lead-free variant or accept the exemption. For a repair or legacy production run, the non-compliant status may not be a blocker.
