MAX4244ESD+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4244ESD+T is a quad, micropower operational amplifier from the MAX4240–MAX4244 family. It operates from a single +1.8V to +5.5V supply or dual ±0.9V to ±2.75V supplies. Key electrical parameters include a 90kHz gain-bandwidth product, 10µA supply current per amplifier, and 200µV input offset voltage. The device features Beyond-the-Rails inputs and rail-to-rail outputs. It is housed in a 14-pin SO package and operates over an extended temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status through manufacturer certificates. Ensure the component matches the exact part number for pinout and electrical specifications. Check for any recent lifecycle changes or obsolescence notices directly from Analog Devices.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring ultra-low voltage operation down to 1.8V with precision signal conditioning. The quad configuration reduces board space compared to single-channel alternatives. Consider the 90kHz bandwidth for low-frequency sensor interfaces. Verify that the 10µA quiescent current meets strict power budget constraints for portable devices.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4240–MAX4244 family of micropower op amps designed for portable electronics. The family offers single, dual, and quad configurations with varying shutdown capabilities. The MAX4244 specifically provides four amplifiers without a shutdown feature, distinguishing it from the MAX4241 and MAX4243 variants which include low-power shutdown modes.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same family include the MAX4240 (single), MAX4242 (dual), and MAX4243 (dual with shutdown). Cross-family replacements require matching the 90kHz GBW, 10µA current, and rail-to-rail I/O characteristics. Verify pin compatibility when substituting between different package options like SOT23 or µMAX.
