Product details
Overview
The MAX4027EUD from Maxim Integrated is a triple, 2-channel video multiplexer-amplifier with integrated current-mode feedback amplifiers, each configured for noninverting gain-of-two (+6dB), 200MHz large-signal -3dB bandwidth, 0.012%/0.014° differential gain/phase error, and ±5V dual-supply operation - designed for high-fidelity RGB video routing in KVM, PIP, and broadcast systems.
For engineers reviewing the MAX4027EUD datasheet, MAX4027EUD pinout, MAX4027EUD application, or MAX4027EUD equivalent, this device supports VGA-to-UXGA (1600×1200) resolution, enables fast 15ns channel switching, delivers 1100V/µs slew rate, and provides high-impedance output disable for scalable matrix architectures.
Technical Context
The MAX4027EUD integrates three independent 2:1 analog multiplexers feeding +2V/V closed-loop amplifiers using current-feedback topology, enabling simultaneous selection and gain compensation for RGB signal paths. Each amplifier drives up to two 75Ω back-terminated coaxial loads while maintaining 62MHz large-signal 0.1dB gain flatness and <0.1% settling in 15ns.
Control logic includes TTL/CMOS-compatible A/B select (channel A/B) and EN enable/disable inputs, both internally pulled down via 17kΩ resistors. The device operates across -40°C to +85°C with guaranteed ±1.25V input voltage range and 2pF constant input capacitance per channel regardless of selection state.

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4028EUD | Same pinout, but gain-of-one (unity) configuration; no internal gain compensation for back termination | Requires external gain stage for coaxial driving; better suited for buffered pass-through vs. terminated line driving | Select MAX4028EUD only if unity-gain signal integrity is required and back-termination loss is handled elsewhere |
| THS7374IPWPR | Quad-channel, 3.3V single-supply operation; 150MHz bandwidth; no integrated mux; requires external logic | Needs external 2:1 mux IC and level-shifting for ±5V systems; lower power but higher BOM complexity | Choose THS7374IPWPR for low-voltage, quad-output designs where space permits discrete mux integration |
Compared with MAX4027EUD, MAX4028EUD removes gain compensation but retains identical switching performance and layout, while THS7374IPWPR trades integrated multiplexing for lower supply voltage and higher channel count - making MAX4027EUD optimal for ±5V RGB routing with coaxial drive capability.

FAQ
What is the operating supply voltage range for the MAX4027EUD?
The MAX4027EUD operates from ±4.5V to ±5.5V dual supplies, with typical performance specified at ±5V. Exceeding ±6V absolute maximum ratings risks permanent damage. The device draws 24mA (ICC) and 21mA (IEE) under normal operation at +25°C, and quiescent current drops to 17mA/15mA in disable mode when EN is high. This supply range aligns with legacy video equipment rails and supports robust operation across the full -40°C to +85°C temperature range.
Does the MAX4027EUD support VGA-to-UXGA resolution video signals?
Yes, the MAX4027EUD supports VGA-to-UXGA (1600×1200) resolution video signals. Its 200MHz large-signal -3dB bandwidth and 62MHz large-signal 0.1dB gain flatness ensure minimal amplitude distortion across the full pixel clock spectrum (up to ~108MHz for UXGA). Combined with 0.012%/0.014° differential gain/phase error and 15ns channel-switching time, the MAX4027EUD preserves color fidelity and timing integrity required for high-resolution graphics and broadcast applications.
How does the MAX4027EUD handle output disabling and what is the disabled output impedance?
Driving the EN pin high places all three amplifier outputs of the MAX4027EUD into high-impedance state, reducing supply current and isolating outputs in matrix configurations. The disabled output resistance is 1.6kΩ (typical), measured at VOUT = −2.5V to +2.5V with EN = 5V. This value includes the internal feedback network and enables safe parallel connection of multiple MAX4027EUDs on shared buses without signal contention or loading effects.
What is the function of the A/B pin and how is it biased?
The A/B pin selects between Channel A (IN1A/IN2A/IN3A) and Channel B (IN1B/IN2B/IN3B) inputs for all three amplifiers simultaneously. A logic-low (≤0.8V) or unconnected A/B pin selects Channel A; a logic-high (≥2.0V) selects Channel B. The pin features an internal 17kΩ pull-down resistor to GND, ensuring default Channel A selection without external biasing - simplifying design in systems where Channel A is the primary path.
Can the MAX4027EUD drive two 75Ω back-terminated coaxial loads simultaneously?
Yes, the MAX4027EUD is explicitly designed to drive up to two 75Ω back-terminated coaxial video loads per channel. Its +2V/V fixed gain compensates for the 6dB loss introduced by double termination, delivering full signal amplitude to the destination. The amplifier maintains 0.012%/0.014° differential gain/phase error and 62MHz 0.1dB gain flatness under this load condition, meeting broadcast video standards for RGB and YPbPr signals routed over coaxial infrastructure.
