MAX4254ESD+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4254ESD+ is a quad-channel, low-noise, low-distortion operational amplifier from the MAX4249–MAX4257 family. It features rail-to-rail outputs and single-supply operation from 2.4V to 5.5V. The device draws 400µA of quiescent supply current per amplifier. It has a gain-bandwidth product of 3MHz and is unity-gain stable. Input offset voltage is typically 70µV with an input bias current of 1pA. It operates over a temperature range of -40°C to +85°C and is housed in a 14-pin SOIC package.

• Medical Instrumentation
• ADC Buffers
• Digital Scales/Strain Gauges

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ESD+' indicates a lead-free/RoHS-compliant package variant. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the package type matches the required 14-pin SOIC footprint. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple low-noise channels are required in a compact form factor. It is suitable for battery-powered designs due to its low quiescent current. Unlike other members of the family, it lacks a shutdown pin, so power management must be handled externally if needed. Ensure the application requires unity-gain stability rather than higher bandwidth decompensated variants.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4249–MAX4257 series of UCSP, single-supply, low-noise, low-distortion, rail-to-rail op amps. The series offers various configurations including single, dual, and quad amplifiers in packages like SOT23, µMAX, and SOIC. The MAX4254 specifically provides four amplifiers in a 14-pin SOIC package, distinguishing it from the single-channel MAX4255 or dual-channel MAX4256.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacement options within the same family include the MAX4254EUA+ (10-pin µMAX) or MAX4254ESD+ (14-pin SOIC). Verify that the alternative package fits the board layout. Other quad amplifiers in the series may not exist; check datasheet selector guides for equivalent channel counts.
