MAX9541AEE+

Video Amps And Modules Overview

The MAX9541AEE+ is a quadruple-channel, 2:1 video mux amplifier housed in a 16-pin QSOP package. It operates from a single 2.7V to 3.6V supply and features integrated lowpass filters optimized for standard-definition video signals. The device provides a fixed voltage gain of 2V/V with input sync-tip clamps that set the internal DC level at approximately 0.3V. Quiescent supply current is typically 21mA, reducing to 35µA in shutdown mode. It supports AC-coupled inputs and DC- or AC-coupled outputs.

Video Amps And Modules Feature Summary

• Integrates lowpass reconstruction filters optimized for standard-definition video signals
• Includes input sync-tip clamps to restore internal DC levels
• Provides a fixed voltage gain of 2V/V
• Features a low-power shutdown mode

Video Amps And Modules Applications

• Standard-definition video signal routing
• Anti-alias filtering before analog-to-digital conversion
• Reconstruction filtering after digital-to-analog conversion

Video Amps And Modules Procurement Notes

Verify the component matches the exact part number MAX9541AEE+. Confirm the presence of the lead-free suffix (+) and the 16-pin QSOP package code E16-4. Ensure the manufacturer is Analog Devices Inc./Maxim Integrated. Check datasheet specifications against your system requirements for operating temperature range and supply voltage limits.

Video Amps And Modules Selection Notes

Select this component when standard-definition video routing requires integrated anti-aliasing or reconstruction filtering. The MAX9541AEE+ is suitable for applications needing a fixed 2V/V gain and sync-tip clamping. If VGA support without filtering is required, consider the MAX9542 variant instead. Verify power consumption constraints align with the quiescent and average power specifications.

Video Amps And Modules Part Context

The MAX9541AEE+ belongs to the MAX9541/MAX9542 family of quadruple 2:1 mux amplifiers designed for video applications. Manufactured by Maxim Integrated (now part of Analog Devices), these devices are intended for handling multiple video channels within a single package. The AEE+ designation specifies the industrial temperature range and lead-free packaging.

Video Amps And Modules Replacement Considerations

The MAX9542AEE+ is a direct functional substitute if integrated lowpass filtering is not required. Both share identical pinouts and electrical characteristics except for the filter implementation.

Video Amps And Modules FAQ

What is the purpose of the input sync-tip clamps?

The input sync-tip clamps restore the DC level of the video signal after it passes through AC-coupling capacitors, setting the internal DC level to approximately 0.3V.

How does the MAX9541AEE+ handle unselected inputs?

Unselected inputs are biased at VDD/3 to prevent forward biasing of ESD diodes and present negligible loading on the video source, ensuring no distortion of signals driving other circuits.
