It delivers an 800 kHz gain-bandwidth product with a 1V/µs slew rate, rail-to-rail output swing, and draws 410 µA supply current. The input bias current is 0.1 pA, and the input offset voltage is 800 µV.
The 800 kHz gain-bandwidth product and 1V/µs slew rate define the usable frequency range for small-signal and large-signal applications respectively. For a unity-gain buffer or active filter, expect clean closed-loop response up to roughly 100 kHz. With 0.1 pA input bias current, the MAX4400ASA loads high-impedance sources like photodiodes or pH probes minimally, preserving signal integrity. The 30 mA output current per channel provides enough drive for ADC inputs or modest loads.
The wide temperature range ensures stable offset and bias performance across thermal extremes without derating.
