MAX4027EUD+

Video Amps And Modules Overview

The MAX4027EUD+ is a triple, wideband video amplifier with integrated input multiplexing. It features three independent 2:1 non-inverting multiplexers configured for a fixed internal gain of +2V/V (+6dB). The device operates from ±5V supplies and provides a small-signal -3dB bandwidth of 225MHz and a large-signal -3dB bandwidth of 200MHz. Key performance metrics include a slew rate of 1100V/µs, a channel-switching time of 15ns, and low differential gain/phase errors of 0.012%/0.014°. It supports VGA to UXGA resolutions and drives two back-terminated video loads.

Video Amps And Modules Feature Summary

• Integrates three high-speed 2:1 multiplexers with fixed internal gain of +2V/V
• Provides fast channel switching with 15ns transition times and minimal transients
• Features high-impedance output disable mode to minimize interaction in parallel arrays
• Maintains excellent video fidelity with low differential gain and phase errors

Video Amps And Modules Applications

• Video source selection and multiplexing
• Picture-in-picture (PIP) insertion systems
• Crosspoint expansion matrices
• Coaxial cable drivers
• Keyboard-Video-Mouse (KVM) switches

Video Amps And Modules Procurement Notes

Verify the specific package suffix matches the required form factor, as the EUD designation indicates a 14-pin TSSOP variant. Confirm that the supply voltage requirements align with your system design, as the device requires dual ±5V rails. Ensure that board layout guidelines regarding ground planes and bypass capacitors are strictly followed to maintain signal integrity at high frequencies.

Video Amps And Modules Selection Notes

Select this component when designing video routing systems requiring simultaneous amplification and switching. The fixed +2V/V gain compensates for losses associated with back-terminated coaxial cables. Consider the high-impedance disable feature if constructing large switch matrices where multiple devices share common output lines without causing signal degradation or loading issues.

Video Amps And Modules Part Context

This part belongs to the MAX4027 family of video multiplexer-amplifiers manufactured by Analog Devices / Maxim Integrated. It is designed specifically for broadcast and graphics video applications. The device combines analog signal processing with digital control logic, allowing TTL/CMOS-compatible inputs to manage channel selection and output enabling within a single integrated circuit.
