MAX4190EUA

Video Amps And Modules Overview

The MAX4190EUA is a single-channel, low-power, current-feedback video amplifier featuring high-speed disable/enable functionality. It operates from a +5V single supply or ±2.25V to ±5.5V dual supplies, consuming 1.5mA per amplifier and delivering ±55mA output current. Optimized for closed-loop gains of +2V/V or greater, it provides an 185MHz -3dB bandwidth and 85MHz gain flatness up to 0.1dB. The device offers a 350V/µs slew rate, 22ns settling time to 0.1%, and fast enable/disable times of 35ns/120ns with minimal switching transients.

Video Amps And Modules Feature Summary

• High-speed disable mode isolates inputs and places outputs in a high-impedance state while reducing supply current.
• Optimized for closed-loop gains of +2V/V or greater with excellent video specifications including low differential gain and phase errors.
• Low power consumption suitable for portable and battery-powered equipment with high output drive capability.

Video Amps And Modules Applications

• High-Definition Surveillance Video
• High-Speed Switching/Multiplexing
• Portable/Battery-Powered Video/Multimedia Systems
• High-Speed Analog-to-Digital Buffers

Video Amps And Modules Procurement Notes

Verify the specific suffix 'EUA' against official documentation to confirm package type (8-pin µMAX) and temperature range (-40°C to +85°C). Ensure compatibility with required supply voltages and feedback network configurations for the target gain setting. Confirm lead-free status if RoHS compliance is mandatory for the application.

Video Amps And Modules Selection Notes

Select this component when a single-channel current-feedback amplifier with integrated high-speed disable is required. It is suitable for applications demanding low glitch during switching and high linearity at video frequencies. Consider the 8-pin µMAX package for space-constrained designs requiring single-channel performance.

Video Amps And Modules Part Context

The MAX4190 is part of the MAX4188/MAX4189/MAX4190 family of low-glitch, high-speed current-feedback amplifiers. While the MAX4188 and MAX4189 are triple-channel devices in 16-pin packages, the MAX4190 is a single-channel variant housed in an 8-pin µMAX package. All variants share similar electrical characteristics optimized for video and signal processing applications.

Video Amps And Modules FAQ

What is the typical supply current in normal operation?

The quiescent supply current is typically 1.5mA per amplifier.

How does the disable function affect the amplifier's output?

When disabled, the inputs are isolated and the outputs are placed in a high-impedance state.
