MAX4292EUA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4292EUA-T is a dual-channel micropower operational amplifier from the MAX4291/MAX4292/MAX4294 family. It operates on a single supply of 1.8V to 5.5V or dual supplies of ±0.9V to ±2.75V, consuming only 100µA per amplifier. The device features rail-to-rail input and output capabilities, a 500kHz gain-bandwidth product, and a typical input offset voltage of ±200µV. Packaged in an 8-pin µMAX format, it provides high precision for low-voltage portable applications.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-Rail Input/Output: Extends common-mode range to both supply rails with outputs swinging within 46mV of rails under load.
• Micropower Operation: Consumes only 100µA per amplifier while maintaining high open-loop voltage gain.
• Ultra-Small Packaging: Available in space-saving 8-bump UCSP and 8-pin µMAX packages.
• High Precision: Features low input offset voltage (±200µV) and no phase reversal for overdriven inputs.

Instrumentation, Op Amps, Buffer Amps Applications

• Two-cell battery-operated systems
• Portable electronic equipment
• Battery-powered instrumentation
• Digital scales
• Strain gauges

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging versus the standard tube configuration. Confirm the 'E' grade corresponds to the -40°C to +85°C temperature range. Ensure the manufacturer designation matches Analog Devices/Maxim Integrated specifications for the MAX4292 series.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-small footprint and low power consumption are critical alongside rail-to-rail signal handling. It is suitable for designs requiring operation down to 1.8V single-supply voltages. Consider the 500kHz bandwidth and 100µA quiescent current balance for general-purpose low-voltage amplification tasks.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4292EUA-T belongs to the MAX4291/MAX4292/MAX4294 family of micropower op amps. While the MAX4291 offers a single channel in SC70/SOT23 and the MAX4294 provides four channels, the MAX4292 specifically delivers dual-channel performance in compact µMAX or UCSP packages for space-constrained designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include other dual-channel micropower op amps with similar 1.8V-5.5V operating ranges and rail-to-rail I/O. Verify pinout compatibility between µMAX and alternative small-outline packages before substitution.
