MAX4314EEE+

Video Amps And Modules Overview

The MAX4314EEE+ is a high-speed, low-power video multiplexer-amplifier from Analog Devices. It integrates a 4-channel multiplexer with a fixed +2V/V gain amplifier in a 16-pin QSOP package. Operating from a single +4V to +10.5V supply, it features a 127MHz -3dB bandwidth and a 430V/µs slew rate. The device offers 40ns channel switching time, ultra-low 10mVp-p switching transients, and rail-to-rail outputs. It includes a low-power shutdown mode reducing current to 560µA.

Video Amps And Modules Feature Summary

• Integrates a 4-channel multiplexer with a fixed +2V/V gain amplifier optimized for driving back-terminated cables
• Features ultra-low 10mVp-p switching transients and 40ns channel switching time for precise video signal routing
• Provides rail-to-rail output swing with input common-mode range extending to the negative supply rail
• Includes a low-power shutdown mode that minimizes supply current and places outputs in a high-impedance state

Video Amps And Modules Applications

• Video signal multiplexing and crosspoint switching
• Driving 75Ω video cables with back-termination
• Broadcast video systems requiring high fidelity
• Flash ADC input buffering for high-speed data acquisition
• Medical imaging and multimedia product signal processing

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements and logic levels before integration. Consult the latest datasheet for layout guidelines to maintain performance at high frequencies.

Video Amps And Modules Selection Notes

Select this component when a fixed +2V/V gain is required for driving terminated video lines. Compare bandwidth and power consumption against adjustable-gain variants if flexibility is needed. Consider the 16-pin QSOP footprint for space-constrained designs requiring four independent channels.

Video Amps And Modules Part Context

This device belongs to the MAX4310–MAX4315 family of single-supply mux-amps. While sharing similar architecture and performance characteristics, members are distinguished by channel count and gain configuration. The MAX4314 specifically combines four inputs with a fixed gain stage, differentiating it from adjustable-gain counterparts.

Video Amps And Modules Replacement Considerations

Official substitutes within the same family include the MAX4312EEE+ for adjustable gain or the MAX4315EEE+ for eight-channel capacity. Verify pinout compatibility and electrical specifications before substitution.

Video Amps And Modules FAQ

What is the typical quiescent supply current in normal operation?

The quiescent supply current is typically 6.9mA.

How does the device handle capacitive loads on the output?

An isolation resistor (RISO) should be used between the output and the load to maintain stability when driving significant capacitive loads.
