MAX4327EUB+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4327EUB+ is a dual-channel, low-power operational amplifier from the Maxim Integrated family. It features rail-to-rail input and output capabilities, operating 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 650µA quiescent current per amplifier. The device incorporates a shutdown mode reducing supply current to 25µA with high-impedance outputs. It offers a typical offset voltage of 700µV, 94dB CMRR, and stability with capacitive loads up to 500pF.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type (µMAX) and temperature range (-40°C to +85°C) against design requirements. Confirm that the shutdown control pin functionality aligns with system power management needs. Ensure compatibility with available PCB footprints for the 10-pin µMAX configuration before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel amplification with rail-to-rail I/O is required in space-constrained designs. The integrated shutdown feature makes it suitable for battery-operated applications where power conservation during idle states is critical. Consider the 5MHz bandwidth and 2V/µs slew rate for moderate-speed signal processing tasks.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4327EUB+ belongs to the MAX432x family of single/dual/quad op amps. This series combines wide bandwidth with excellent DC accuracy. The EUB+ suffix indicates a dual-channel version in a 10-pin µMAX package with an extended industrial temperature range. It shares core specifications with other variants like the MAX4326 and MAX4329 but differs in channel count and packaging.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the MAX4326EUA (dual, µMAX) and MAX4326ESA (dual, SO). For quad-channel requirements, consider the MAX4329ESD. Verify pinout compatibility and thermal characteristics when transitioning between package types.
