Product details
Overview
The MAX4311EEE from Maxim Integrated is a 4-channel, unity-gain-stable video multiplexer-amplifier with 345MHz -3dB bandwidth, 430V/µs slew rate, and 40ns channel switching time. It features rail-to-rail outputs, input common-mode range extending to the negative rail, and ultra-low 10mVp-p switching transients-optimized for broadcast video signal routing in professional AV equipment.
For engineers reviewing the MAX4311EEE datasheet, MAX4311EEE pinout, MAX4311EEE application, or MAX4311EEE equivalent, key selection criteria include differential gain/phase error (0.06%/0.08°), shutdown current (560µA), output drive into 150Ω (±95mA), and QSOP-16 package compatibility with high-density video PCB layouts.
Technical Context
The MAX4311EEE integrates a 4:1 analog multiplexer with an adjustable-gain voltage-feedback amplifier optimized for closed-loop gains ≥+1V/V. Its internal architecture maintains 8Ω open-loop output impedance across full output swing, minimizing load-dependent gain error and bandwidth variation.
It supports single-supply operation from +4V to +10.5V (or ±2V to ±5.25V dual supply), delivers rail-to-rail output swing (within 730mV of VCC and 30mV of VEE into 150Ω), and achieves 0.05dB gain matching between channels over its 345MHz bandwidth.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4312EEE | 8-channel mux, 265MHz bandwidth, 7.4mA quiescent current | Higher channel count but lower bandwidth; suited for multi-input monitoring vs. high-fidelity routing | Select when system requires >4 inputs and can trade 80MHz bandwidth for density |
| THS7374IPW | 4-channel, fixed +6dB gain, 100MHz bandwidth, integrated 75Ω driver | Lacks programmable gain and has lower bandwidth; optimized for cost-sensitive consumer video | Select for fixed-gain, lower-bandwidth applications where THS7374's integrated termination reduces BOM count |
Compared with MAX4312EEE and THS7374IPW, the MAX4311EEE uniquely balances 4-channel flexibility, 345MHz bandwidth, and adjustable gain-making it optimal for professional broadcast routing where fidelity and configurability are prioritized over channel count or integration.

FAQ
What is the maximum operating supply voltage for the MAX4311EEE?
The MAX4311EEE operates from a single supply of +4V to +10.5V or dual supplies of ±2V to ±5.25V. Absolute maximum supply voltage is 12V (VCC to VEE). Exceeding this risks permanent damage. The device delivers specified performance across its full rated range, including rail-to-rail output swing and 345MHz bandwidth at +5V.
Does the MAX4311EEE support DC-coupled video inputs?
Yes, the MAX4311EEE supports DC-coupled video inputs because its input common-mode voltage range extends to the negative supply rail (VEE). When operated on a single +5V supply with VEE = GND, inputs can swing from 0V to +2.2V-fully accommodating baseband composite, Y/C, or RGB video signals without AC coupling or level-shifting circuitry.
How does the MAX4311EEE achieve low switching transients?
The MAX4311EEE achieves 10mVp-p switching transients through matched transistor pairs in its 4:1 multiplexer core and charge-balanced switching architecture. This minimizes glitch energy during channel transitions, preventing visible artifacts in video waveforms. The specification is measured under standard conditions (VOUT = 2Vp-p, RL = 150Ω) and confirmed across temperature.
Can the MAX4311EEE drive 75Ω coaxial cables directly?
Yes, the MAX4311EEE can drive 75Ω coaxial cables directly when used with proper back-termination. Its rail-to-rail output delivers ±95mA into 30Ω and swings to within 730mV of VCC into 150Ω-enabling clean 1Vp-p video levels into 75Ω loads. For optimal flatness, use external 75Ω series termination at the driver output per Figure 5 in the datasheet.
What is the function of the FB pin on the MAX4311EEE?
On the MAX4311EEE, the FB (feedback) pin connects to the inverting input of the output amplifier and is used with external resistors to set closed-loop gain (≥+1V/V). Unlike fixed-gain variants (e.g., MAX4314), the MAX4311EEE requires external RF and RG resistors tied between OUT–FB and FB–GND. Layout best practices mandate minimal capacitance at FB to avoid peaking or instability.
