What is MAX4403AUD+ used for?
The MAX4403AUD+ is ideal for battery-powered portable instruments and IoT sensor nodes where four amplifier channels are needed with minimal supply current. Its rail-to-rail output and single-supply operation allow it to work efficiently from 3.3 V or 5 V rails, and the per-channel shutdown capability lets the system disable unused amplifiers to extend battery life in duty-cycled applications.

Frequently Asked Questions
What is the input bias current specification of the MAX4403AUD+, and why does it matter for high-impedance sensors?
The MAX4403AUD+ has a maximum input bias current of 0.1 nA (100 pA) at 25°C, which causes negligible voltage error even with source impedances in the megaohm range. For high-impedance sensors such as pH electrodes or piezoelectric transducers that can have source impedances exceeding 1 MΩ, this low bias current ensures less than 0.1 mV of offset error.
How does the shutdown feature of the MAX4403AUD+ help in duty-cycled portable applications?
The MAX4403AUD+ includes a shutdown control that disables the amplifier outputs and reduces supply current to a standby level, allowing the host system to power down amplifier channels that are not actively measuring. In a sensor hub that polls channels sequentially, enabling only the active channel drops the total op-amp supply current by up to 75% compared to keeping all 4 channels running continuously.
What common-mode rejection ratio does the MAX4403AUD+ provide, and how does it benefit noisy industrial environments?
The MAX4403AUD+ achieves a typical CMRR of 84 dB and a guaranteed minimum of 68 dB across its operating range. This high rejection level attenuates 50 Hz or 60 Hz power-line interference and ground-loop noise by a factor of more than 2500:1, making it reliable for amplifying small differential sensor signals in industrial settings where supply and ground rails carry significant noise.
