MAX4315EEE+T

Video Amps And Modules Overview

The MAX4315EEE+T is a high-speed, low-power video multiplexer-amplifier from Analog Devices. It integrates an 8-channel input multiplexer with a fixed +2V/V gain amplifier in a 16-pin QSOP package. Operating on a single supply of +4V to +10.5V or dual supplies of ±2V to ±5.25V, it features a 97MHz -3dB bandwidth and 310V/µs slew rate. The device offers 40ns channel switching time, 10mVp-p switching transients, and rail-to-rail outputs. Quiescent current is 7.4mA typical, reducing to 560µA in shutdown mode.

Video Amps And Modules Feature Summary

• Integrates 8-channel multiplexer with fixed +2V/V gain amplifier
• Rail-to-rail output capability for wide dynamic range
• Ultra-low switching transients ensure signal integrity
• Low-power shutdown mode minimizes energy consumption

Video Amps And Modules Applications

• Video signal multiplexing systems
• Broadcast video crosspoint switching matrices
• 75Ω video cable drivers for back-terminated lines
• Flash ADC input buffering stages
• Medical imaging signal processing chains

Video Amps And Modules Procurement Notes

Verify the specific suffix EEE corresponds to the 16-pin QSOP package and industrial temperature range (-40°C to +85°C). Confirm that the + symbol indicates lead-free compliance as per manufacturer standards. Ensure compatibility with existing board layouts requiring surface-mount technology.

Video Amps And Modules Selection Notes

Select this part when eight simultaneous video channels require amplification. The fixed +2V/V gain is optimized for driving back-terminated cables. Compare against adjustable gain variants if system requirements differ. Consider the 16-pin QSOP footprint constraints during mechanical design integration.

Video Amps And Modules Part Context

This component belongs to the MAX4310–MAX4315 family of mux-amps designed for broadcast video applications. While sharing core architecture with lower-channel counterparts, the MAX4315 specifically provides eight inputs. It complements the MAX4314 by offering higher channel density within the same package form factor.

Video Amps And Modules Replacement Considerations

Direct replacements include other members of the MAX431x family such as MAX4314EEE+T for 4-channel applications. Cross-reference pinouts carefully as channel counts vary. Verify that alternative parts maintain the required +2V/V fixed gain specification for impedance matching.

Video Amps And Modules FAQ

How does the fixed +2V/V gain affect bandwidth compared to unity-gain models?

The fixed +2V/V configuration results in a lower -3dB bandwidth of 97MHz compared to the 265MHz–345MHz bandwidth of the unity-gain variants, optimizing performance for driving back-terminated cables.

What is the input common-mode voltage range?

The input common-mode range extends from the negative supply rail (VEE) to VCC minus 2.7V, allowing ground-sensing operation in single-supply systems.
