MAX4312ESE

Video Amps And Modules Overview

The MAX4312ESE is a high-speed, low-power video multiplexer-amplifier from the MAX4310–MAX4315 family. It integrates an 8-channel multiplexer with an adjustable gain amplifier optimized for unity-gain stability. Operating on a single +4V to +10.5V supply, it features a 265MHz -3dB bandwidth and up to 345V/µs slew rate. The device offers 40ns channel switching time, ultra-low 10mVp-p switching transients, and rail-to-rail outputs in a 16-pin Narrow SO package.

Video Amps And Modules Feature Summary

• Features ultra-low 10mVp-p switching transients for clean signal routing
• Provides rail-to-rail output capability driving loads to within 730mV of the rails
• Includes a low-power shutdown mode reducing supply current significantly

Video Amps And Modules Applications

• Video signal multiplexing
• Video crosspoint switching
• Flash ADC input buffering
• Broadcast video systems
• Medical imaging equipment

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct temperature range and package type. Confirm availability status through authorized distribution channels as product lifecycle status may vary. Ensure compatibility with existing board layouts regarding the 16-pin Narrow SO footprint.

Video Amps And Modules Selection Notes

Select this component when eight independent video channels require switching with minimal signal distortion. The adjustable gain configuration suits applications needing unity-gain stability. Consider the low quiescent current and shutdown feature for power-sensitive designs requiring efficient energy management during idle periods.

Video Amps And Modules Part Context

This device belongs to the MAX4310–MAX4315 series of single-supply mux-amps. While other family members offer fixed gains or different channel counts, the MAX4312 specifically combines eight inputs with flexible gain settings. This distinguishes it from the MAX4315 which shares the eight-channel count but utilizes a fixed +2V/V gain architecture.

Video Amps And Modules Replacement Considerations

Official substitutes within the same family include the MAX4315ESE for fixed-gain applications or the MAX4311EEE for four-channel requirements. Verify pin compatibility and electrical specifications before substitution to maintain system performance integrity.

Video Amps And Modules FAQ

What is the maximum operating supply voltage for the MAX4312ESE?

The device operates from a single supply voltage ranging from +4V to +10.5V.

How does the MAX4312ESE handle logic-level inputs for channel selection?

It uses three address logic inputs (A0, A1, A2) to select one of the eight channels, with thresholds defined relative to the supply rails.

What is the typical switching transient magnitude during channel changes?

The device exhibits ultra-low switching transients of 10mVp-p, ensuring minimal disturbance to the video signal during multiplexing.
