MAX4242EUA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4242EUA-T is a dual-channel micropower operational amplifier from the MAX4240–MAX4244 family. It operates on a single +1.8V to +5.5V supply or dual ±0.9V to ±2.75V supplies, consuming 10µA per amplifier. Key electrical parameters include a 90kHz gain-bandwidth product, 40V/ms slew rate, and 70nV/√Hz input voltage noise density. The device features Beyond-the-Rails inputs extending 200mV beyond each rail and rail-to-rail outputs. It is housed in an 8-pin µMAX package and guaranteed for operation from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Beyond-the-Rails input common-mode range extends 200mV beyond both supply rails.
• Rail-to-rail output stage allows full power-supply voltage utilization for signal range.
• Ultra-low power consumption of 10µA per amplifier enables extended battery life.
• Unity-gain stable with capacitive loads up to 200pF.

Instrumentation, Op Amps, Buffer Amps Applications

• Two-cell battery-powered systems
• Portable/battery-powered electronic equipment
• Sensor amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm that the 'T' suffix indicates tape-and-reel packaging if required by assembly processes. Ensure compatibility with the intended supply voltage and load conditions before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low-voltage operation and minimal power consumption. The dual-channel configuration is suitable for space-constrained designs needing two independent amplification paths. Verify that the 90kHz bandwidth meets the signal frequency requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4240–MAX4244 family of micropower op amps. The MAX4242 specifically provides two channels in an 8-pin µMAX package. Unlike the MAX4241/MAX4243, it does not feature a shutdown mode. It shares the same core electrical characteristics as other members of the series.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Other members of the MAX4240–MAX4244 family may serve as functional replacements depending on channel count and package requirements. Verify pinout compatibility and ensure the substitute part matches the required operating temperature range and supply voltage specifications.
