MAX4287EUA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4287EUA is a dual-channel, high-speed voltage-feedback operational amplifier designed for driving analog-to-digital converters. It operates from a single +2.85V to +6.5V supply or ±1.425V to ±3.25V dual supplies with a quiescent current of 20mA per amplifier. Key electrical parameters include a 250MHz small-signal bandwidth, 350V/µs slew rate, and 6ns settling time to 0.1%. The device features an input common-mode range extending to the negative rail and provides up to 106mA output drive. It lacks a disable feature and is housed in an 8-pin µMAX package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'EUA' corresponds to the 8-pin µMAX package and -40°C to +85°C temperature range. Confirm that the absence of a disable pin matches system requirements, as this variant does not support low-power shutdown states unlike other members of the family. Ensure compatibility with existing board layouts utilizing the µMAX form factor.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4287EUA when dual channels are required without the need for a high-speed disable function. This part is suitable for applications needing unity-gain stability and high output drive capability. Consider alternative models like the MAX4288 if active low-power shutdown control is necessary for the design.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the MAX4285–MAX4288/MAX4387/MAX4388 family of +3V/+5V, 250MHz ADC buffer amplifiers. While sharing core high-speed characteristics with the series, the MAX4287 specifically omits the disable feature found in the MAX4285, MAX4286, MAX4288, and MAX4388 variants. It is internally compensated for unity-gain stability.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same package and feature set are not explicitly listed in the provided documentation. Designers may consider the MAX4387EUA for gain-of-five compensation or the MAX4288EUB if a disable pin is acceptable.
