MAX4237AEUA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4237AEUA-T is a high-precision operational amplifier featuring an ultra-low offset voltage of 20µV (max) and drift of 2µV/°C (max). It operates on single supplies from +2.4V to +5.5V with rail-to-rail output swing and ground-sensing inputs. The device includes a shutdown function reducing quiescent current to less than 0.1µA. It offers a gain-bandwidth product of 7.5MHz, stable for closed-loop gains greater than 5V/V, and handles up to 200pF capacitive loads.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm that the 'AEUA' designation corresponds to the Grade A performance specifications within the µMAX package. Ensure compatibility with existing board layouts regarding the 8-pin footprint and thermal dissipation requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high DC precision without chopper stabilization techniques. The MAX4237 variant is appropriate where higher bandwidth is needed compared to the unity-gain stable MAX4236. Consider the shutdown feature for battery-operated designs requiring extended standby life.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4236/MAX4237 family of very high precision, 3V/5V rail-to-rail op amps. These devices utilize BiCMOS technology to achieve exceptional DC accuracy. The family provides options for different stability requirements and packaging formats to suit various space-constrained electronic designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes include other Maxim Integrated high-precision CMOS op amps with similar shutdown capabilities and rail-to-rail outputs. Verify pinout compatibility and ensure replacement parts meet the required 20µV offset voltage specification for Grade A performance.
