MAX4310ESA+

Video Amps And Modules Overview

The MAX4310ESA+ is a high-speed, low-power video multiplexer-amplifier from the Analog Devices/Maxim Integrated MAX4310–MAX4315 family. It integrates a 2-channel input multiplexer with an adjustable-gain output amplifier optimized for unity-gain stability. Operating from a single +4V to +10.5V supply or dual ±2V to ±5.25V supplies, it features rail-to-rail outputs and an input common-mode range extending to the negative rail. Key electrical specifications include a 280MHz -3dB bandwidth, 460V/µs slew rate, and 40ns channel switching time with ultra-low 10mVp-p switching transients. Quiescent supply current is typically 6.1mA, reducing to 560µA in shutdown mode.

Video Amps And Modules Feature Summary

• Integrates a 2-channel multiplexer with an adjustable-gain amplifier optimized for closed-loop gains of +1V/V or greater.
• Features rail-to-rail voltage-feedback output amplifiers with low open-loop output impedance to minimize gain error under load.
• Provides ultra-low switching transients of 10mVp-p and short 40ns channel switching times suitable for video applications.
• Includes a low-power shutdown mode that places outputs in a high-impedance state and significantly reduces supply current.

Video Amps And Modules Applications

• Video signal multiplexing
• Video crosspoint switching
• Broadcast video systems
• 75Ω video cable drivers

Video Amps And Modules Procurement Notes

Verify the device marking code matches the MAX4310 designation and confirm the suffix 'E' indicates the industrial temperature range of -40°C to +85°C. Ensure the package type corresponds to the 8-pin SO specification. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and electrical characteristics before integration into final designs.

Video Amps And Modules Selection Notes

Select the MAX4310ESA+ when a 2-channel configuration with adjustable gain is required. Choose this part over fixed-gain variants (MAX4313 series) if system flexibility allows for external feedback resistor selection. Consider the 8-pin SO package constraints regarding thermal dissipation and board space compared to larger packages available for higher channel counts within the same family.

Video Amps And Modules Part Context

This component belongs to the MAX4310–MAX4315 family of single-supply mux-amps designed for high-speed video applications. The family differentiates models by channel count (2, 4, or 8) and amplifier gain configuration (adjustable vs. fixed +2V/V). The MAX4310 specifically serves as the entry-level 2-channel model with adjustable gain, offering a compact solution for multi-channel video routing where gain adjustment is necessary.

Video Amps And Modules Replacement Considerations

Direct functional substitutes within the same family include the MAX4310EUA, which shares identical electrical characteristics but utilizes an 8-pin µMAX package instead of the SO package. Other family members like the MAX4311 or MAX4312 offer higher channel counts but maintain similar performance metrics.
