Analog Devices Inc./Maxim Integrated MAX4310EUA

Overview

The MAX4310EUA from Maxim Integrated is a 2-channel, single-supply video multiplexer-amplifier with adjustable-gain amplifier optimized for unity-gain stability, 280MHz -3dB bandwidth, 460V/µs slew rate, and 40ns channel switching time. It operates from +4V to +10.5V single supply, delivers rail-to-rail output swing into 150Ω, and achieves 0.06% differential gain / 0.08° differential phase error - making it suitable for broadcast-quality SD/HD video routing in professional AV equipment.

For engineers reviewing the MAX4310EUA datasheet, MAX4310EUA pinout, MAX4310EUA application, or MAX4310EUA equivalent, key selection considerations include its 2-channel mux architecture with ground-sensing inputs, low 10mV_p-p switching transient, shutdown current of 560µA, and µMAX-8 package compatibility with high-density PCB layouts.

Technical Context

The MAX4310EUA integrates a 2:1 analog multiplexer with an internally compensated voltage-feedback amplifier configurable for ≥+1V/V closed-loop gain. Its input common-mode range extends to the negative rail (VEE), enabling true ground-referenced video signal handling without level-shifting circuitry.

Channel selection is controlled via TTL/CMOS-compatible A0 logic input; SHDN enables low-power shutdown mode, placing the output in high-impedance state. The amplifier maintains 8Ω open-loop output impedance across full voltage range, minimizing load-dependent gain error and bandwidth variation typical of rail-to-rail output stages.

Key Specifications

Pinout & Package

The MAX4310EUA is housed in an 8-pin µMAX® package (3mm × 3mm, 0.8mm height), compatible with standard SO-8 footprints but offering 40% smaller area and improved thermal performance.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for demanding industrial, communications, and consumer applications.

The MAX4310–MAX4315 family was developed specifically for high-speed, low-glitch video signal routing in single-supply systems - targeting broadcast, medical imaging, and multimedia equipment where differential gain/phase accuracy and fast switching are mandatory.

FAQ

What is the maximum operating supply voltage for the MAX4310EUA?

The MAX4310EUA supports a single-supply operating voltage range of +4V to +10.5V. Absolute maximum supply voltage (VCC to VEE) is 12V. Exceeding +10.5V may degrade long-term reliability or cause parametric shift; operation above 12V risks permanent damage. For dual-supply use, ±2V to ±5.25V is specified, with VEE tied to ground in single-supply configurations.

Does the MAX4310EUA require external gain-setting resistors?

Yes, the MAX4310EUA uses external feedback (RF) and input (RG) resistors to set closed-loop gain ≥+1V/V. Unlike the fixed-gain MAX4313EUA, it has no internal gain resistors. Recommended values (e.g., RF = RG = 500Ω for +2V/V) are provided in the datasheet to optimize bandwidth and stability; surface-mount 1% tolerance resistors are required for production consistency.

Can the MAX4310EUA drive a 75Ω coaxial cable directly?

Yes, the MAX4310EUA can drive a 75Ω coaxial cable directly when configured with proper back-termination. Its rail-to-rail output delivers ≥1.2Vpp into 75Ω with <0.06% differential gain error, meeting SMPTE 259M requirements. Layout best practices - including 50Ω microstrip traces, local 100nF bypassing, and avoidance of ground-plane voids near FB pin - are essential to maintain signal integrity.

What is the input common-mode voltage range of the MAX4310EUA?

The MAX4310EUA features a ground-sensing input with common-mode range extending from VEE (ground in single-supply mode) to VCC – 2.8V. This allows DC-coupled video signals with 0V black level reference without level-shifting circuitry. Operation beyond this range increases switching time and introduces nonlinearity but does not cause phase reversal or latch-up.

How does the shutdown function affect the output impedance of the MAX4310EUA?

When SHDN is driven low, the MAX4310EUA places its output in a high-impedance state with typical disabled output resistance of 35kΩ. This enables safe paralleling of multiple MAX4310EUA outputs on a shared bus - only the active device drives the line while others present negligible loading, supporting scalable video matrix architectures without external analog switches.
