MAX4041ESA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4041ESA-T is a single-channel micropower operational amplifier from the MAX4040–MAX4044 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +2.4V to +5.5V supply or dual ±1.2V to ±2.75V supplies, consuming only 10µA per amplifier. The device features rail-to-rail input and output capabilities, a 90kHz gain-bandwidth product, and a low-power shutdown mode reducing current to under 1µA. Packaged in an 8-pin SOIC, it functions within an extended temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and thermal management needs before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for portable applications requiring minimal power draw and full signal swing near supply rails. The shutdown feature is critical for battery life extension. Verify that the 90kHz bandwidth meets the application's frequency response requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4040–MAX4044 family of low-cost, micropower op amps. The family includes single, dual, and quad configurations in SOT23 and SO packages. The MAX4041 specifically offers a single amplifier with a shutdown pin, distinguishing it from the non-shutdown MAX4040.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official manufacturer substitution guides for confirmed equivalents. Direct replacements must maintain the same pinout, shutdown functionality, and electrical characteristics within the specified operating conditions.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the shutdown mode affect the amplifier output?

When the SHDN pin is pulled low, the supply current drops to less than 1µA per amplifier, and the outputs enter a high-impedance state.

What is the input offset voltage specification?

The input offset voltage is typically 200µV at +25°C, with a maximum drift of 2µV/°C over the operating temperature range.
