MAX4189ESD+

Video Amps And Modules Overview

The MAX4189ESD+ is a triple, low-power, current-feedback video amplifier in a 14-pin SO package. It operates from +5V single or ±2.25V to ±5.5V dual supplies, consuming 1.5mA per amplifier. Optimized for closed-loop gains of +1V/V or greater, it provides a 250MHz -3dB bandwidth and 30MHz gain flatness. The device features high-speed disable/enable modes (120ns/35ns), reducing supply current to 450µA while isolating inputs and placing outputs in a high-impedance state.

Video Amps And Modules Feature Summary

• Triple-channel architecture optimized for unity-gain (+1V/V) applications
• High-speed enable/disable mode with fast switching transients
• Low quiescent power consumption suitable for portable systems
• Excellent video specifications including low differential gain and phase errors

Video Amps And Modules Applications

• High-Definition Surveillance Video
• High-Speed Switching/Multiplexing
• Portable/Battery-Powered Video/Multimedia Systems
• Professional Cameras
• CCD Imaging Systems

Video Amps And Modules Procurement Notes

Verify the specific suffix 'ESD+' indicates a lead-free 14-pin SO package rated for -40°C to +85°C operation. Confirm that the triple-channel configuration matches system requirements, as single and dual variants exist within this family. Ensure the application circuit supports the required feedback network for optimal performance at the specified gain.

Video Amps And Modules Selection Notes

Select the MAX4189ESD+ when a triple-channel solution is required for video signals with a closed-loop gain of +1V/V or higher. This model offers superior bandwidth compared to the MAX4188 variant. Verify that the 14-pin SO package fits the PCB layout constraints and that the thermal dissipation capabilities are sufficient for the operating environment.

Video Amps And Modules Part Context

This component belongs to the MAX4188/MAX4189/MAX4190 family of low-glitch, 250MHz current-feedback amplifiers. While the MAX4188 is optimized for gains of +2V/V and the MAX4190 is a single-channel device, the MAX4189 specifically targets unity-gain applications. All variants share similar low-power characteristics and high-speed disable functionality.

Video Amps And Modules Replacement Considerations

Direct functional replacements include the MAX4188ESD+ for triple-channel applications requiring higher gain optimization, or the MAX4190ESD+ for single-channel needs. Cross-referencing pinouts and electrical characteristics against the original design is essential before substitution.
