MAX4189EEE+

Video Amps And Modules Overview

The MAX4189EEE+ is a triple, low-power, current-feedback video amplifier housed in a 16-pin QSOP 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 175V/µs slew rate. The device features high-speed disable/enable modes with 120ns/35ns transition times, reducing supply current to 450µA while isolating inputs and placing outputs in a high-impedance state.

• High-speed analog-to-digital buffering
• Portable and battery-powered multimedia systems
• CCD imaging systems
• RGB distribution amplifiers

Video Amps And Modules Procurement Notes

Verify the specific suffix EEE+ indicates lead-free construction and the 16-pin QSOP package configuration. Confirm the operating temperature range matches the -40°C to +85°C specification. Ensure the design supports the required single or dual supply voltages and that the disable logic thresholds align with the system control signals.

Video Amps And Modules Selection Notes

Select this component when a triple-channel solution is required for video multiplexing or distribution at unity gain. The current-feedback topology offers superior speed compared to voltage-feedback alternatives. Consider the disabled output leakage and isolation characteristics if the application involves high-frequency signal switching or strict crosstalk requirements.

Video Amps And Modules Part Context

This part belongs to the MAX4188/MAX4189/MAX4190 family of low-glitch video amplifiers. While the MAX4188 targets gains of +2V/V and the MAX4190 is a single-channel variant, the MAX4189 specifically addresses triple-channel designs requiring optimal performance at +1V/V gain. All variants share similar disable functionality and low-power characteristics.

Video Amps And Modules Replacement Considerations

Direct functional substitutes within the same family include the MAX4188EEE+ for higher gain applications and the MAX4190EEE+ for single-channel needs. Verify pin compatibility and thermal dissipation requirements when transitioning between package types or channel counts.
