Product details

The MAX4451EKA+ is a dual voltage-feedback op-amp from Maxim, built for high-speed signal conditioning where settling time and slew rate matter. The rail-to-rail output stage lets it drive an ADC full-scale range or a video load without headroom loss, which is the difference between a clean sync pulse and a clipped one.

Dual channel in a SOT-23-8 — space savings without sacrificing speed

Two amplifiers in a single SOT-23-8 package, each channel drawing 6.5 mA supply current. Input bias current runs 6.5 µA and input offset voltage is 4 mV — typical for a high-speed voltage-feedback topology, but worth noting if you are DC-coupling a precision baseline.

Surface-mount assembly in SOT-23-8, which is a common footprint for dense mixed-signal boards.

Frequently asked questions

Is MAX4451EKA+ rail-to-rail output?

Yes, the output type is rail-to-rail, which allows the output to swing close to the supply rails — useful for single-supply ADC driving or video clamp circuits.

What is the slew rate of MAX4451EKA+?

The slew rate is 485 V/µs, which supports fast voltage swings needed for composite video and pulse applications.

Can I use MAX4451EKA+ in a high-speed video application?

Yes, with a 210 MHz -3 dB bandwidth and 485 V/µs slew rate, it is well-suited for composite video line drivers and high-speed pulse amplifiers.
