MAX4236AESA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4236AESA is a high-precision, single-channel operational amplifier manufactured by Analog Devices/Maxim Integrated in an 8-pin SO package. It operates on a supply voltage range of +2.4V to +5.5V with a quiescent current of 350µA. The device features a gain-bandwidth product of 1.7MHz and a slew rate of 0.3V/µs. Key electrical specifications include a maximum input offset voltage of ±20µV at +25°C (Grade A) and a temperature coefficient of ±2µV/°C. Input bias current is typically 1pA, while the open-loop voltage gain reaches 128dB. The amplifier supports rail-to-rail output swing and includes a shutdown function reducing current to less than 0.1µA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific Grade A designation and SO-8 packaging configuration when sourcing. Confirm that the component matches the official Maxim Integrated part number structure. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Cross-reference datasheet revisions to guarantee parameter consistency.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high DC precision with low power consumption. The unity-gain stability makes it suitable for buffer configurations. Consider the shutdown feature for battery-operated systems where standby current must be minimized. Verify that the 1.7MHz bandwidth meets the signal frequency requirements.

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 single-supply systems. Unlike chopper-stabilized amplifiers, it achieves low offset through CMOS input stage design. The MAX4236 variant is unity-gain stable, distinguishing it from the higher-speed MAX4237 which requires gains greater than 5V/V.
