240V/µs slew rate in a 5-pin SC-70
The MAX4352EXK+T is a single voltage-feedback op-amp from Maxim that delivers a 240V/µs slew rate and 80 MHz -3dB bandwidth while drawing only 620 µA of supply current. That combination — high speed at low quiescent — makes it a candidate for video buffers, ADC drivers, or any signal path where the board is tight on power and area. Input offset voltage is 400 µV typical, input bias current 800 nA. It comes in a 5-lead SC-70 package (also known as SOT-353), surface-mount only.
Package and mounting
The 240V/µs slew rate handles large-signal swings up into the tens of megahertz without visible slew-rate limiting. Paired with the 80 MHz -3dB bandwidth, the small-signal gain stays flat past 10 MHz. That is enough for composite video (NTSC/PAL), high-speed DAC output buffers, or pulse-processing circuits where edge rates matter. The 620 µA supply current is the trade-off — you get the speed without the 5–10 mA draw of older video op-amps, but the SC-70 package limits dissipation to about 200 mW at 85°C. Do not try to drive 50 Ω back-terminated lines directly; use it as a high-impedance buffer into a cable driver stage.
