MAX11505CUB+

Video Processing Overview

The MAX11505CUB+ is a four-channel standard-definition video filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply within the 0°C to +70°C commercial temperature range and is housed in a 10-pin µMAX package. Each channel features a 5th order lowpass filter with an 8.6MHz typical -3dB bandwidth, except for Channel 1 which provides a 0.8dB high-frequency boost resulting in an 8.9MHz bandwidth. The device includes transparent input clamps compatible with AC- or DC-coupled signals and output buffers with +6dB gain capable of driving two standard 150Ω video loads.

Video Processing Feature Summary

• Four-channel architecture with 5th order lowpass filters optimized for standard-definition video applications
• Integrated transparent input clamps supporting both AC- and DC-coupled signal inputs
• +6dB gain output buffers designed to drive dual standard 150Ω video loads
• High ESD protection rating of 12kV HBM on outputs

Video Processing Applications

• Set-top box receivers
• Digital video recorders (DVRs)
• Security video systems
• DVD players
• Personal video recorders

Video Processing Procurement Notes

Verify that the specific component variant matches the required frequency response characteristics, as the MAX11505 differs from the MAX11504 by providing a 0.8dB peaking passband response specifically on Channel 1. Confirm the package code corresponds to the 10-pin µMAX format and ensure the operating temperature range aligns with commercial specifications. Cross-reference the manufacturer part number against official distributor databases to confirm current availability status.

Video Processing Selection Notes

Select this component when designing standard-definition video signal chains requiring anti-aliasing or DAC smoothing functions. The MAX11505 is appropriate for applications needing a slight high-frequency boost on the primary video channel to compensate for system rolloff, while maintaining flat responses on auxiliary channels. Ensure the design accommodates the single +5V power supply requirement and thermal dissipation limits associated with driving multiple video loads simultaneously.

Video Processing Part Context

This device belongs to the MAX11504/MAX11505 family of four-channel standard-definition video filters. While sharing identical physical packaging and core filtering topology, the MAX11505 distinguishes itself through its specific Channel 1 frequency response profile. This differentiation allows designers to choose between a strictly flat passband characteristic found in the MAX11504 or the boosted response offered by the MAX11505 based on specific video processing requirements.

Video Processing Replacement Considerations

The MAX11504CUB+ serves as a direct functional substitute if the 0.8dB high-frequency boost on Channel 1 is not required. Both devices share the same pinout, package dimensions, and electrical interface, differing only in the frequency response specification of the first channel.
