MAX4315EEE+

Video Amps And Modules Overview

The MAX4315EEE+ 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 from +4V to +10.5V, it features a 97MHz -3dB bandwidth and a 310V/µs slew rate. The device offers 40ns channel switching time with ultra-low 10mVp-p transients. Quiescent current is 7.4mA, reducing to 560µA in shutdown mode.

Video Amps And Modules Feature Summary

• Integrates an 8-channel multiplexer with a fixed +2V/V gain amplifier optimized for driving back-terminated cables
• Features rail-to-rail outputs that drive loads to within 730mV of the supply rails
• Provides excellent video specifications with differential gain and phase errors of 0.09% and 0.03° respectively
• 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 drivers
• 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 by checking the latest environmental certification documents provided by the manufacturer.

Video Amps And Modules Selection Notes

Select this component when an 8-channel video switch with fixed amplification is required. The fixed +2V/V gain makes it suitable for driving back-terminated cables without external feedback resistors. Compare bandwidth and power consumption against adjustable-gain variants if signal conditioning flexibility is needed instead of fixed amplification.

Video Amps And Modules Part Context

This device belongs to the MAX4310–MAX4315 family of single-supply mux-amps. While sharing similar architecture and performance characteristics, each part is distinguished by its specific number of multiplexer inputs and amplifier gain configuration. The MAX4315 specifically combines eight channels with a fixed gain stage.

Video Amps And Modules Replacement Considerations

The MAX4315ESE is an alternative pin-compatible package option within the same series offering identical electrical performance. Verify that any substitute maintains the 16-pin QSOP or SO footprint and matches the +2V/V fixed gain requirement for direct interchangeability.

Video Amps And Modules FAQ

What is the quiescent supply current for the MAX4315?

The typical quiescent supply current is 7.4mA, which reduces to 560µA when the low-power shutdown mode is activated.

How does the MAX4315 handle capacitive loads?

For high-capacitive loads, an isolation resistor should be used between the output and the load to maintain stability and prevent peaking in the frequency response.
