MAX4313EUA

Video Amps And Modules Overview

The MAX4313EUA is a high-speed, low-power video multiplexer-amplifier from the MAX4310–MAX4315 family. It integrates a 2-channel analog multiplexer with a fixed +2V/V gain amplifier in an 8-pin µMAX package. Operating from a single +4V to +10.5V supply or dual ±2V to ±5.25V supplies, it features a 150MHz -3dB bandwidth and a 540V/µs slew rate. The device offers rail-to-rail outputs, a quiescent current of 6.1mA, and a low-power shutdown mode reducing current to 560µA.

Video Amps And Modules Feature Summary

• Integrates a 2-channel multiplexer with a fixed +2V/V gain amplifier optimized for driving back-terminated cables
• Features ultra-low 10mVp-p switching transients and a 40ns channel switching time
• 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
• Video crosspoint switching
• 75Ω video cable drivers

• Broadcast video systems

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with existing board layouts regarding the 8-pin µMAX footprint. Confirm availability through authorized distribution channels as supply status may vary.

Video Amps And Modules Selection Notes

Select this component when a fixed +2V/V gain is required for driving terminated video lines. Compare against the MAX4310 series if adjustable gain is needed instead. Consider the 150MHz bandwidth and 540V/µs slew rate for high-frequency signal integrity requirements.

Video Amps And Modules Part Context

This part belongs to the MAX4310–MAX4315 family of single-supply mux-amps. While other family members offer different channel counts or adjustable gains, the MAX4313 specifically provides two inputs with a fixed internal gain setting. This configuration simplifies circuit design for applications requiring consistent amplification without external feedback resistors.

Video Amps And Modules Replacement Considerations

The MAX4313ESA is the SOIC package equivalent within the same family. Other family members like the MAX4310 or MAX4314 differ in channel count or gain configuration and are not direct functional substitutes without schematic modification.

Video Amps And Modules FAQ

What is the fixed voltage gain of the MAX4313?

The MAX4313 has a fixed voltage gain of +2V/V (6dB), internally set by thin-film resistors.

How does the shutdown mode affect the output impedance?

In shutdown mode, the output is placed in a high-impedance state, typically around 35kΩ, while the supply current reduces to 560µA.
