Product details
Overview
MAX4267EUA-T 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 driving 100Ω. It operates from +4.5V to +8.0V single supply and delivers ±45mA output current, making it suitable for high-frequency ADC drivers in RF telecom infrastructure.
For engineers reviewing the MAX4267EUA-T datasheet, MAX4267EUA-T pinout, MAX4267EUA-T application, or MAX4267EUA-T equivalent, key selection criteria include gain-stability requirement (+5V/V), disable-mode timing (100ns enable / 750µs disable), 8nV/√Hz input voltage noise, and µMAX-8 package thermal performance in space-constrained signal chains.
Technical Context
The MAX4267EUA-T uses proprietary bipolar process technology to achieve low distortion in single-supply operation, with decompensated architecture enabling higher loop gain at +5V/V closed-loop gain. Its input common-mode range extends from (VEE + 1.6V) to (VCC – 1.6V), and output swings to within 1.1V of rails under 100Ω load.
It features active-low disable control that reduces quiescent current to 1.6mA per amplifier and places outputs in high-impedance state. The device maintains stability with capacitive loads up to 22pF when used with recommended isolation resistors, and exhibits 0.1dB gain flatness to 55MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 300MHz - supports wideband IF and baseband signal conditioning up to UHF frequencies |
| Slew Rate | 900V/µs - enables clean 1V step response with 1ns rise/fall time for fast transient fidelity |
| SFDR @ 100MHz | -47dBc - ensures minimal spurious content in high-frequency DAC/ADC interfaces |
| Input Voltage Noise | 8nV/√Hz - preserves SNR in low-level analog front-ends like IF amplifiers |
| Output Drive | ±45mA - sustains full swing into 100Ω loads without clipping in high-speed line drivers |
| Disable Current | 1.6mA per amp - reduces system power by >90% during idle periods in burst-mode systems |
| Gain Stability | Min +5V/V - requires external gain-setting network; not unity-gain stable |
Pinout & Package
The MAX4267EUA-T is housed in an 8-pin µMAX® package (3mm × 3mm, 0.8mm height), optimized for high-density RF and communications PCB layouts with exposed pad for thermal dissipation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DISABLE | Active-low enable control; logic low disables amplifier and places output in high-Z state |
| 2 | IN– | Inverting input terminal; referenced to VEE for differential signal processing |
| 3 | IN+ | Noninverting input terminal; supports rail-to-rail common-mode range (VEE+1.6V to VCC–1.6V) |
| 4 | VEE | Negative supply pin; connect to ground in single-supply operation |
| 5 | VCC | Positive supply pin; accepts +4.5V to +8.0V; bypass with 1nF || 0.1µF ceramic |
| 6 | OUT | Amplifier output; drives 100Ω load to within 1.1V of rails; high-Z when DISABLE = low |
| 7 | N.C. | No internal connection; leave unconnected or tie to ground for mechanical stability |
| 8 | Exposed Pad | Thermal pad; must be soldered to PCB ground plane for thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8009ARZ | Unity-gain stable; 1GHz GBW; higher 1.8nV/√Hz noise; no disable function | Requires different compensation network; unsuitable for +5V/V fixed-gain designs without external feedback tuning | Select when unity-gain stability and wider bandwidth outweigh disable functionality and lower noise requirements |
| LMH6629MA/NOPB | Compensated for +5V/V; 1.5GHz GBW; 1.9nV/√Hz noise; no disable pin; SOIC-8 package | Lacks active disable mode; larger SOIC-8 footprint increases parasitic inductance at >100MHz | Choose for highest bandwidth where disable control is unnecessary and board area permits SOIC packaging |
Compared with AD8009ARZ and LMH6629MA/NOPB, the MAX4267EUA-T uniquely combines +5V/V gain stability, integrated disable control, 8nV/√Hz noise, and µMAX-8 thermal performance-making it optimal for space-constrained, power-gated RF signal chains requiring deterministic gain accuracy.

FAQ
What is the minimum stable gain configuration for the MAX4267EUA-T?
The MAX4267EUA-T is internally compensated for a minimum stable closed-loop gain of +5V/V. It is not unity-gain stable, and attempting to operate it at gains below +5V/V may result in oscillation or degraded phase margin. Gain-setting resistors must be selected accordingly-e.g., RG = 125Ω and RF = 500Ω for nominal +5V/V noninverting configuration per the datasheet.
Does the MAX4267EUA-T support single-supply operation?
Yes, the MAX4267EUA-T operates from a single +4.5V to +8.0V supply. In this configuration, VEE is connected to ground, and the input common-mode range spans from +1.6V to (VCC – 1.6V). Output swing reaches within 1.1V of both rails under 100Ω load, enabling true single-supply signal chain design without level-shifting circuitry.
How does the disable function behave on the MAX4267EUA-T?
The MAX4267EUA-T features an active-low DISABLE pin (Pin 1). When pulled low, it reduces quiescent supply current to 1.6mA per amplifier and places the output in a high-impedance state. Enable time is typically 100ns; disable time is 750µs. This function supports power gating in time-division systems and eliminates signal contention during multiplexer switching.
What is the maximum capacitive load the MAX4267EUA-T can drive stably?
The MAX4267EUA-T remains stable with capacitive loads up to 22pF when used with an appropriate series isolation resistor (e.g., 6Ω for 22pF, per Figure 2 in the datasheet). Without isolation, peaking exceeds 2dB above 15pF. For coaxial cable or PCB trace capacitance, the isolation resistor must be placed directly at the output pin to preserve phase margin.
Is the MAX4267EUA-T pin-compatible with other devices in the MAX4265–MAX4270 family?
Yes-the MAX4267EUA-T shares identical 8-pin µMAX pinout with MAX4265EUA-T and MAX4266EUA-T, including DISABLE, IN–, IN+, VEE, VCC, OUT, N.C., and exposed pad. However, gain compensation differs: MAX4265 is unity-gain stable, MAX4266 requires ≥+2V/V, and MAX4267 requires ≥+5V/V. Swapping without adjusting external feedback violates stability requirements.
