MAX4471ESA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4471ESA-T is a dual micropower operational amplifier from the MAX4464/MAX4470/MAX4471 family. It operates on a single +1.8V to +5.5V supply with a typical supply current of 750nA per amplifier. The device features ground-sensing inputs, rail-to-rail output swing, and unity-gain stability. Key electrical parameters include a 9kHz gain-bandwidth product, 2V/ms slew rate, ±7mV input offset voltage, and 11mA output drive capability.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the component matches the required RoHS compliance specifications for the target assembly process.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring ultra-low power operation in space-constrained designs. The dual configuration offers two amplifiers in an 8-pin SO package. Verify that the 9kHz bandwidth meets signal processing requirements. Consider the 11mA output drive capability for load interfacing needs.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4470 family of micropower op amps designed for single-supply operation. The family includes single, dual, and quad variants with varying bandwidths. The MAX4471 specifically provides dual amplifiers optimized for low-voltage, low-current portable applications while maintaining high open-loop gain and stability.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the MAX4470 (single channel) and MAX4472 (quad channel). Other family members like MAX4464 and MAX4474 offer higher bandwidth but require different minimum closed-loop gains.
