MAX4265ESA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4265ESA is a single-channel, ultra-low-distortion voltage-feedback operational amplifier from the Maxim Integrated MAX4265–MAX4270 family. It operates from a single +4.5V to +8.0V supply or dual ±2.25V to ±4.0V supplies. The device features a small-signal bandwidth of 400MHz and a full-power bandwidth of 270MHz. It delivers an input voltage noise density of 8nV/√Hz and a slew rate of 900V/µs. The amplifier includes a low-power disable mode that reduces quiescent current to 1.6mA per amplifier and places outputs in a high-impedance state. It is housed in an 8-pin SO package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Ultra-low distortion performance with superior spurious-free dynamic range (SFDR) capabilities for high-fidelity signal processing.
• Integrated active-low disable mode that significantly reduces power consumption and isolates outputs when inactive.
• Capable of driving heavy loads, including 100Ω resistive loads, while maintaining wide bandwidth and DC accuracy.
• Unity-gain stable design optimized for applications requiring minimal external component count.

Instrumentation, Op Amps, Buffer Amps Applications

• Base-station amplifiers
• High-frequency ADC drivers
• RF telecom applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ESA' corresponds to the 8-pin SO package and -40°C to +85°C temperature range. Confirm RoHS compliance status as indicated in official documentation. Ensure the source document explicitly lists this part number before procurement to avoid substitution errors.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4265ESA for designs requiring unity-gain stability and maximum bandwidth within the family. Consider decompensated variants if higher closed-loop gains are used. Evaluate the disable feature requirements against system power management needs. Verify load capacitance limits to ensure stability without additional isolation resistors.
