MAX9502MELT+T

Video Amps And Modules Overview

The MAX9502MELT+T is a low-power video amplifier with an integrated reconstruction filter, operating from a single 2.5V to 3.6V supply. It features a fixed voltage gain of +12dB and consumes 5.3mA quiescent current. The device incorporates a 4th-order Chebyshev lowpass filter with a 5.5MHz passband and provides 55dB attenuation at 27MHz. It utilizes a 6-pin μDFN package (1mm x 1.5mm x 0.8mm) and supports an active-low shutdown mode reducing current to 0.01μA.

Video Amps And Modules Feature Summary

• Integrates a 4th-order Chebyshev reconstruction filter directly with the output amplifier to minimize board space.
• Provides DC-coupled input and output connections, allowing direct interfacing with video digital-to-analog converters.
• Features internal short-circuit protection that activates when output current exceeds 95mA.
• Includes an active-low shutdown pin to reduce supply current to 0.01μA for power conservation.

Video Amps And Modules Applications

• Mobile Phones
• Digital Still Cameras
• Portable Video Devices
• Security/CCTV Systems

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix ELT corresponds to the 6-pin μDFN package and -40°C to +85°C temperature range. Confirm RoHS compliance status indicated by the plus sign in the part number. Ensure the selected variant matches the required +12dB gain specification for the application design.

Video Amps And Modules Selection Notes

Select this component when a fixed +12dB gain is required for driving standard 150Ω video loads. Consider the MAX9502GEXK+T if a +6dB gain or SC-70-5 package is preferred. Evaluate the extended temperature range variants if operation beyond +85°C is necessary for automotive or industrial environments.

Video Amps And Modules Part Context

This device belongs to the MAX9502 family of small, low-power video amplifiers designed for portable applications. The family includes variants with different gains (+6dB and +12dB) and packages (SC-70-5 and μDFN-6). These components are engineered to replace discrete passive reconstruction filters, simplifying circuit layouts in battery-powered consumer electronics.

Video Amps And Modules Replacement Considerations

Direct substitutes within the same family include MAX9502GAALT+T and MAX9502MAALT+T for extended temperature ranges. For alternative gain configurations, consider MAX9502GELT+T (+6dB) or MAX9502MEXK+T (SC-70-5 package). Verify pin compatibility and thermal requirements before substitution.

Video Amps And Modules FAQ

What is the maximum input voltage range for the MAX9502M at 3.0V supply?

At a 3.0V supply voltage, the MAX9502M input voltage range extends from ground to 0.6V.

How does the device handle output short circuits?

Internal short-circuit protection activates if output current exceeds 95mA, shutting off the output for 12μs and turning it on for 0.8μs until the short is removed.
