MAX4286ESA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4286ESA is a single-channel, voltage-feedback operational amplifier designed for high-speed analog-to-digital converter (ADC) buffering. It operates from a single +2.85V to +6.5V supply or dual ±1.425V to ±3.25V supplies. The device features a small-signal bandwidth of 150MHz and a slew rate of 350V/µs. It includes a high-speed disable function that reduces quiescent current and places outputs in a high-impedance state. Internally compensated for gains of +5V/V or greater, it offers low distortion with an 88dBc SFDR at 5MHz.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation before integration. Confirm that the operating temperature range meets the environmental requirements of the target application. Ensure proper bypassing and layout practices are followed to maintain stability and performance specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel amplifier with a gain of +5V/V or higher is required. It is suitable for designs needing fast settling times and low distortion at moderate bandwidths. Consider alternative models within the family if unity-gain stability or dual-channel configurations are necessary instead.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX4285–MAX4288/MAX4387/MAX4388 series of +3V/+5V, 250MHz ADC buffer amplifiers. The series provides options for single and dual channels with varying bandwidths and compensation settings. The MAX4286 specifically targets applications requiring higher closed-loop gains while maintaining high-speed operation.
