Product details
Overview
The MAX4311ESD-T from Maxim Integrated is a 4-channel, unity-gain-stable video multiplexer-amplifier optimized for broadcast-quality signal routing. It delivers 345MHz -3dB bandwidth, 40ns channel switching time, and ultra-low 10mVp-p switching transients, enabling clean SD/HD video multiplexing in professional AV switchers and medical imaging front-ends.
For engineers reviewing the MAX4311ESD-T datasheet, MAX4311ESD-T pinout, MAX4311ESD-T application, or MAX4311ESD-T equivalent, key selection criteria include its rail-to-rail output swing into 150Ω, input common-mode range extending to VEE, differential gain/phase error of 0.06%/0.08°, and compatibility with single +4V to +10.5V supplies - all critical for 75Ω video cable driver and flash ADC buffer designs.
Technical Context
The MAX4311ESD-T integrates a 4-input 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 typical of rail-to-rail amplifiers.
It features logic-controlled channel selection (A0/A1), shutdown control (SHDN), and operates with input common-mode voltage down to the negative rail. The device achieves 0.06% differential gain and 0.08° differential phase error at 3.58MHz, meeting broadcast video fidelity requirements without external calibration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4311EEE | Same core specs but in 16-pin QSOP; 0.06%/0.08° DG/DP, 345MHz BW, 40ns switching | QSOP offers better thermal dissipation and higher pin pitch for rework; narrower SO preferred for dense layouts | Select MAX4311ESD-T for space-constrained SOIC-N14 footprint; choose MAX4311EEE for thermal-limited or hand-soldered assemblies |
| THS7374IPW | 4-channel, 150MHz BW, fixed +6dB gain, 0.15% DG error, no shutdown mode | Lacks SHDN and has lower bandwidth; optimized for fixed-gain cable driving, not mux flexibility | Use THS7374IPW only when fixed +2V/V gain suffices and shutdown is unnecessary; MAX4311ESD-T preferred for programmable gain and low-power standby |
Compared with MAX4311EEE and THS7374IPW, the MAX4311ESD-T uniquely balances 345MHz bandwidth, 40ns switching, shutdown capability, and SOIC-N14 compactness - making it optimal for next-gen HD video switchers requiring both speed and board-area efficiency.

FAQ
What is the maximum operating supply voltage for the MAX4311ESD-T?
The MAX4311ESD-T supports a maximum supply voltage of +10.5V on VCC relative to VEE. Absolute maximum rating is 12V between VCC and VEE. Operation beyond +10.5V may degrade parametric performance or reliability, and is not guaranteed per datasheet specifications. Always maintain VCC within 4.0V to 10.5V for full compliance with AC/DC electrical characteristics.
Does the MAX4311ESD-T support dual-supply operation?
Yes, the MAX4311ESD-T supports dual-supply operation from ±2V to ±5.25V. In this configuration, VCC connects to +VS and VEE connects to –VS, enabling symmetric headroom for bipolar video signals. The input common-mode range extends to the negative rail, and rail-to-rail output swing remains functional - making it suitable for legacy dual-rail video infrastructure without level-shifting circuitry.
What is the purpose of the FB pin on the MAX4311ESD-T?
The MAX4311ESD-T does not have an FB (feedback) pin. Unlike the MAX4310/MAX4312 variants, the MAX4311ESD-T uses internal feedback for unity-gain stability and does not expose a feedback node. Pin 7 in the 14-pin narrow SO package is GND, not FB. Confusion may arise from family-wide pin descriptions - always verify pin function against the MAX4311-specific pinout table in Rev 3 of the datasheet.
Can the MAX4311ESD-T drive a 75Ω coaxial cable directly?
Yes, the MAX4311ESD-T is explicitly characterized to drive 75Ω video cables with back-termination. Its rail-to-rail output delivers >2Vp-p into 150Ω (two 75Ω in parallel), and its 8Ω open-loop output impedance ensures minimal gain error under load. For optimal flatness, use series isolation resistors (e.g., 27Ω) close to the OUT pin when driving long cables with significant capacitance.
What is the shutdown current consumption of the MAX4311ESD-T?
When SHDN is pulled low, the MAX4311ESD-T reduces quiescent supply current to 560µA (typical), with a maximum of 750µA over temperature. During shutdown, the output enters a high-impedance state (typically 35kΩ), allowing multiple MAX4311ESD-T devices to be paralleled in large video matrices without contention. This enables power-gated operation in battery-powered or thermally sensitive video systems.
