800 kHz gain-bandwidth, rail-to-rail, dual-channel signal chain
The MAX4402ASA+ is an Analog Devices general-purpose operational amplifier with two independent circuits in an 8-SOIC package. It delivers 800 kHz gain-bandwidth product, 1V/µs slew rate, and rail-to-rail output swing — specs that fit low-frequency sensor amplification, active filters, and single-supply buffers where headroom near the supply rails matters.
410 µA supply, picoamp bias, -40 to +125°C
Supply current is 410 µA across both channels, keeping the quiescent draw low enough for multi-channel battery devices. Input bias current of 0.1 pA means negligible DC error when interfacing high-impedance sources like photodiodes or pH probes.
Active production, RoHS3, tube packaging
Parts ship in tube format — typical for low-volume assembly runs and prototyping.
