MAX4312EEE+

Video Amps And Modules Overview

The MAX4312EEE+ is an eight-channel video multiplexer-amplifier from the MAX4310–MAX4315 family, manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 8:1 multiplexer with a unity-gain stable adjustable amplifier in a 16-pin QSOP 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 265MHz -3dB bandwidth, a 345V/µs slew rate, and a quiescent current of 7.4mA typical. It features rail-to-rail outputs, low switching transients, and a low-power shutdown mode reducing current to 560µA.

Video Amps And Modules Feature Summary

• Integrates an 8-channel multiplexer with an adjustable gain amplifier optimized for unity-gain stability
• Features ultra-low 10mVp-p switching transients and fast 40ns channel switching time
• Provides rail-to-rail output capability 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
• Flash ADC input buffering
• 75Ω video cable driving
• Broadcast video systems

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature range. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure compliance with RoHS directives and other regional regulatory requirements before finalizing procurement decisions.

Video Amps And Modules Selection Notes

Select the MAX4312EEE+ when eight input channels are required with an adjustable gain configuration. Compare against the MAX4315EEE+ if a fixed +2V/V gain is preferred for driving back-terminated cables. Consider the MAX4312ESE+ variant if a Narrow SOIC package is more suitable for the PCB layout constraints than the QSOP option.

Video Amps And Modules Part Context

This component belongs to the MAX4310–MAX4315 series of high-speed, low-power, single-supply multichannel video multiplexer-amplifiers. The family differentiates devices by the number of multiplexer inputs (2, 4, or 8) and the amplifier gain configuration (adjustable or fixed +2V/V). This specific part represents the eight-channel adjustable gain variant within this integrated solution family.

Video Amps And Modules Replacement Considerations

The MAX4312ESE+ is an officially confirmed substitute offering identical electrical performance in a 16-Pin Narrow SO package. Verify pin compatibility and thermal characteristics when transitioning between the QSOP and SOIC packages to ensure proper board integration.

Video Amps And Modules FAQ

What is the differential gain and phase error specification for the MAX4312?

The MAX4312 exhibits a differential gain error of 0.06% and a differential phase error of 0.08 degrees, making it suitable for broadcast video applications.

How does the shutdown mode affect the output impedance?

When the SHDN input is driven low, the device enters low-power shutdown mode, placing the output into a high-impedance state with a typical resistance of 35kΩ.
