MAX4125ESA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4125ESA-T is a single-channel, wide-bandwidth operational amplifier from the MAX4122–MAX4129 family. It features a 25MHz gain-bandwidth product and a 10V/µs slew rate. The device operates on a single supply of +2.7V to +6.5V or dual supplies of ±1.35V to ±3.25V. It includes a shutdown function that reduces supply current to 25µA per amplifier while placing outputs in a high-impedance state. Key electrical characteristics include a typical input offset voltage of 200µV, 650µA quiescent current per amplifier, and rail-to-rail input and output capabilities.

• High tolerance for capacitive loads with stability up to 500pF
• No phase reversal for overdriven inputs

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered instruments
• Portable equipment
• Data-acquisition systems
• Signal conditioning
• Low-power, low-voltage applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm the temperature grade matches the required operating environment, as the MAX4125 is available in various industrial and commercial ranges. Ensure the supplier provides valid RoHS compliance documentation consistent with the manufacturer's specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4125ESA-T when a decompensated amplifier stable at gains of 10V/V or greater is required. This part is suitable for precision signal conditioning where high speed and low power consumption are critical. Verify that the application circuit maintains a closed-loop gain of at least 10V/V to ensure stability.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the MAX4122–MAX4129 series of single/dual/quad, wide-bandwidth, low-power, single-supply rail-to-rail I/O op amps. The MAX4125 specifically denotes a single-channel variant within this family that incorporates a shutdown feature and utilizes the 8-pin SO package format.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements within the same family include the MAX4125EUA+ (µMAX package) and MAX4125ESA+ (tube packaging). Other variants like MAX4124 or MAX4128 share similar electrical characteristics but differ in channel count or specific package options.
