485 V/µs slew rate — what it buys you
The MAX4450EXK+T: The 485 V/µs slew rate, paired with a 210 MHz -3 dB bandwidth, places this voltage-feedback amplifier in the high-speed signal path class. It can swing a 5 Vpp output at frequencies well above 10 MHz without slew-rate limiting, which matters for video distribution, ADC front-end buffering, or RF envelope detection. The rail-to-rail output preserves dynamic range on supply rails as low as 4.5 V and up to 11 V.
SC-70-5 footprint and board-fit
Housed in a 5-lead SC-70-5, the MAX4450EXK+T occupies roughly 2.2 mm × 2.4 mm of board area. At these bandwidths, parasitic capacitance from the PCB layout and the feedback resistor values will dominate the closed-loop response more than the amplifier's own input capacitance. ROHS3 compliance is confirmed, clearing EU and global regulatory gates.
Supply current vs output drive
That is a reasonable power budget for a high-speed buffer driving a 50-ohm or 75-ohm terminated line. Input bias current runs 6.5 µA with a 4 mV typical input offset — not a precision DC amplifier, but entirely adequate for AC-coupled high-speed paths where offset is blocked by a series capacitor.
