Product details
Overview
MAX4267EUA from Maxim Integrated is a single-channel, ultra-low-distortion, voltage-feedback operational amplifier compensated for minimum stable gain of +5V/V, featuring 300MHz -3dB bandwidth, 900V/µs slew rate, and -47dBc SFDR at 100MHz when driving a 100Ω load. It operates from +4.5V to +8.0V single supply and delivers ±45mA output current, making it suitable for high-frequency ADC drivers in telecom base-station signal chains.
For engineers reviewing the MAX4267EUA datasheet, MAX4267EUA pinout, MAX4267EUA application, or MAX4267EUA equivalent, key selection criteria include its +5V/V minimum gain stability, disable-mode high-impedance output control, 8nV/√Hz input voltage noise density, and µMAX® package compatibility with space-constrained RF front-end layouts.
Technical Context
The MAX4267EUA employs proprietary bipolar process technology optimized for low-voltage, high-speed operation, enabling superior spurious-free dynamic range while maintaining DC accuracy. Its decompensated architecture provides higher loop gain at +5V/V closed-loop configurations compared to unity-gain variants, directly improving distortion performance and slew rate.
It features an active-low DISABLE pin that reduces quiescent current to 1.6mA per amplifier and places the output in high-impedance state with 100ns enable time and 750µs disable time. Input common-mode range extends from (VEE + 1.6V) to (VCC – 1.6V), and output swing reaches within 1.1V of rails under 100Ω load.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8009ARZ | Unity-gain stable; 1GHz -3dB bandwidth; 5500V/µs slew rate; no disable function; SO-8 package | Requires external gain-setting network for +5V/V; lacks power-gating for burst-mode systems | Select when maximum speed and unity-gain flexibility outweigh need for integrated disable and gain-optimized stability |

FAQ
What is the minimum stable gain of the MAX4267EUA?
The MAX4267EUA is internally compensated for a minimum stable gain of +5V/V. This means it is not unity-gain stable and must be used in closed-loop configurations with gain ≥5 to ensure phase margin and avoid oscillation. Configurations below +5V/V require external compensation and are not supported per datasheet specifications.
Does the MAX4267EUA support single-supply operation?
Yes, the MAX4267EUA operates from a single +4.5V to +8.0V supply. In this mode, VEE pins connect to ground, and the input common-mode range spans (VEE + 1.6V) to (VCC – 1.6V), enabling true single-supply interfacing with microcontrollers and ADCs referenced to the same rail.
What is the SFDR performance of the MAX4267EUA at 100MHz?
The MAX4267EUA achieves -47dBc spurious-free dynamic range at 100MHz when driving a 100Ω load with 1Vp-p output. This value is measured under standard conditions (VCC = +5V, RL = 100Ω to VCC/2, TA = +25°C) and reflects its suitability for high-frequency communication systems where spectral purity is critical.
How does the disable function operate on the MAX4267EUA?
The MAX4267EUA features an active-low DISABLE pin (Pin 1). When pulled to VEE (ground), it reduces quiescent supply current to 1.6mA per amplifier and places the output in high-impedance state. Enable time is typically 100ns; disable time is 750µs. The pin accepts standard CMOS logic levels and may be left floating for normal operation.
What package type is used for the MAX4267EUA?
The MAX4267EUA is supplied in an 8-pin µMAX® package (3mm × 3mm, 0.8mm height), a thermally enhanced variant of SO-8 with exposed paddle for improved heat dissipation. It is footprint-compatible with standard SO-8 layouts but offers superior high-frequency performance due to reduced parasitic inductance.
