MAX4314ESD

Video Amps And Modules Overview

The MAX4314ESD 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 14-pin Narrow SO package. The device operates on a single supply of +4V to +10.5V or dual supplies of ±2V to ±5.25V. Key electrical specifications include a 127MHz -3dB bandwidth and a 430V/µs slew rate. Quiescent current is typically 6.9mA, reducing to 560µA in shutdown mode. It features rail-to-rail outputs and an input common-mode range extending to the negative rail.

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 fast 40ns channel switching time
• Provides rail-to-rail output swing with an input common-mode range that includes the negative supply rail
• Includes a low-power shutdown mode that reduces supply current and places outputs in a high-impedance state

Video Amps And Modules Applications

• Video signal multiplexing
• Video crosspoint switching
• Flash ADC input buffering
• 75Ω video cable drivers
• Broadcast video systems

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix 'ESD' corresponds to the 14-pin Narrow SO package and the -40°C to +85°C industrial temperature range as defined in the manufacturer's selector guide. Confirm availability through authorized distribution channels, as component status may vary by region.

Video Amps And Modules Selection Notes

Select this part when a fixed +2V/V gain is required for driving terminated video lines. Compare against the MAX4311ESD if adjustable gain greater than +1V/V is needed instead of the fixed gain configuration. Ensure the 127MHz bandwidth meets the system requirements for the intended video frequency spectrum.

Video Amps And Modules Part Context

This component belongs to the MAX4310–MAX4315 family of single-supply mux-amps. The family differentiates products by the number of multiplexer inputs (2, 4, or 8) and the amplifier gain configuration (adjustable or fixed +2V/V). The MAX4314 specifically combines four input channels with the fixed-gain architecture.

Video Amps And Modules Replacement Considerations

The MAX4314ESE is an alternative within the same family offering identical electrical performance but housed in a 16-pin Narrow SO package. Verify pin compatibility and board layout constraints before substituting between the 14-pin and 16-pin variants.

Video Amps And Modules FAQ

What is the differential gain error specification for the MAX4314?

The differential gain error is typically 0.06% and has a maximum specified value of 0.09%.

How does the device behave when the SHDN pin is driven low?

Driving the SHDN pin low activates the low-power shutdown mode, reducing the quiescent supply current to approximately 560µA and placing the amplifier outputs into a high-impedance state.
