MAX4236AEUA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4236AEUA-T is a high-precision, single-channel operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features an exceptionally low offset voltage of 20µV (max) at +25°C and a temperature coefficient of 2µV/°C (max). The device operates on a single supply voltage ranging from 2.4V to 5.5V with a quiescent current of 350µA. It offers a gain-bandwidth product of 1.7MHz, a slew rate of 0.3V/µs, and rail-to-rail output swing. The input common-mode range extends below the negative supply rail, and it includes a shutdown function reducing current to less than 0.1µA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix '-T' against official documentation to confirm tape-and-reel packaging requirements. Ensure the 'EUA' designation corresponds to the µMAX package and Grade A specifications. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference the manufacturer part number with any updated datasheet revisions to ensure compatibility with existing designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high DC precision and low noise in single-supply systems. The Grade A specification ensures tight offset voltage limits suitable for sensitive sensor interfaces. Consider the shutdown feature for battery-operated devices where power conservation is critical. Verify that the 1.7MHz bandwidth meets the signal frequency requirements of the target application.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX4236/MAX4237 family of very high precision op amps designed for 3V and 5V systems. The MAX4236 variant is unity-gain stable, distinguishing it from the higher-speed MAX4237 which requires a minimum closed-loop gain of 5V/V. Both share similar precision characteristics but differ in bandwidth and stability requirements.

Instrumentation, Op Amps, Buffer Amps FAQ

What is the input common-mode voltage range?

The input common-mode range extends from VEE - 0.15V to VCC - 1.2V, allowing ground sensing in single-supply applications.

How does the shutdown function operate?

Pulling the SHDN pin low reduces quiescent current to less than 0.1µA and places the output in a high-impedance state. Pulling it high enables normal operation with a recovery time of 4µs.

Is the MAX4236AEUA-T unity-gain stable?

Yes, the MAX4236 series is unity-gain stable, whereas the MAX4237 series is stable only for closed-loop gains greater than 5V/V.
