MAX4326EUA+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4326EUA+ is a dual-channel, low-power operational amplifier from the Maxim Integrated family. It operates on single supplies from 2.4V to 6.5V or dual supplies of ±1.2V to ±3.25V. Key electrical parameters include a 5MHz gain-bandwidth product, 2V/µs slew rate, and 700µV typical offset voltage. The device features rail-to-rail input and output capabilities, drawing 650µA per amplifier at 5V. It is housed in an 8-pin µMAX package and supports loads down to 250Ω.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input common-mode range and output voltage swing for low-voltage operation
• Unity-gain stability with capacitive loads up to 500pF
• Low quiescent current consumption of 650µA per amplifier
• High-speed performance with 5MHz gain-bandwidth product

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered data-acquisition instruments
• Portable equipment signal conditioning
• RSSI systems
• PA biasing circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'EUA+' corresponds to the 8-pin µMAX package and -40°C to +85°C temperature range. Confirm RoHS compliance status through official documentation. Ensure the ordering code matches the exact channel count and package style required for the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail I/O is required alongside moderate bandwidth. It is suitable for single-supply applications where power efficiency is critical. Consider the MAX4323 or MAX4327 if shutdown functionality is needed, as the MAX4326 lacks this feature.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4322/MAX4323/MAX4326/MAX4327/MAX4329 family of low-cost, low-power op amps. The MAX4326 specifically provides dual channels without shutdown control, distinguishing it from the MAX4327 which includes independent shutdown pins for both amplifiers.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MAX4327 serves as a functional substitute if shutdown capability is desired. Other family members like the MAX4322 (single) or MAX4329 (quad) offer different channel counts but share similar electrical characteristics.
