MAX4028EWE+

Video Amps And Modules Overview

The MAX4028EWE+ is a triple, 2:1 voltage-feedback multiplexer-amplifier with input clamps and a fixed gain of +2V/V. It operates on a single +5V supply within the -40°C to +85°C temperature range. Key electrical parameters include a 130MHz large-signal bandwidth, 210MHz small-signal bandwidth, and 300V/µs slew rate. The device features 20ns channel switching time and ultra-low ±10mVP-P switching transients. Differential gain and phase errors are limited to 0.2% and 0.4°, respectively. It is housed in a 16-pin Wide SO package.

Video Amps And Modules Feature Summary

• Triple-channel architecture with independently selectable sync-tip or key-clamp inputs for video signal biasing
• Fixed internal gain of +2V/V utilizing thin-film resistors for consistent amplification
• Low-power, high-impedance disable mode that reduces quiescent current and isolates outputs
• Ultra-low switching transients suitable for high-speed video source switching and OSD insertion

Video Amps And Modules Applications

• Video projectors
• Displays and digital televisions
• Broadcast and graphics video systems
• Set-top boxes
• Security systems

Video Amps And Modules Procurement Notes

Verify the specific suffix 'EWE+' corresponds to the 16-pin Wide SO package and extended temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the ordering code matches the triple-channel configuration (MAX4028) rather than the quad-channel variant (MAX4029). Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Video Amps And Modules Selection Notes

Select this component when a triple-channel video switch with integrated clamping is required. The fixed +2V/V gain simplifies circuit design by eliminating external feedback resistors. The adjustable key-clamp voltage allows compensation for different video formats via an external resistor. Ensure the application requires single +5V operation and can accommodate the specified quiescent current levels.

Video Amps And Modules Part Context

This part belongs to the MAX4028/MAX4029 family of video multiplexer-amplifiers. The MAX4028 provides three channels, while the MAX4029 offers four. Both share identical electrical characteristics, including bandwidth, slew rate, and clamping functionality. The EWE+ designation specifies the wide SOIC package and industrial temperature range, distinguishing it from TSSOP variants.

Video Amps And Modules Replacement Considerations

The MAX4028EUE+ serves as a direct package alternative using the 16-pin TSSOP form factor. The MAX4029 series provides quad-channel functionality with identical electrical performance but requires a 20-pin package. Verify pin compatibility and thermal dissipation requirements when substituting between package types.
