MAX7482ETI+

Overview

The MAX7482ETI+ is a bidirectional video filter and buffer integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. Designed for high-frequency signal integrity, this component operates within a frequency range of DC to 160 MHz. It features a low noise figure of 0.5 dB and maintains a typical insertion loss of 0.3 dB at 100 MHz. The device supports a wide supply voltage range from 2.7 V to 5.5 V and draws a maximum supply current of 15 mA. Packaged in a compact 16-lead TSSOP with an exposed pad, it functions effectively as both a filter and a buffer for video signals.

Feature Summary

• Provides bidirectional filtering and buffering capabilities for video signal paths
• Ensures signal integrity through low noise and minimal insertion loss characteristics
• Supports flexible power supply requirements across standard voltage levels

Applications

• Video signal conditioning in display interfaces
• Buffering applications for composite and component video lines
• Signal integrity enhancement in multimedia equipment

Procurement Notes

Verify the specific suffix ETI against the manufacturer's official datasheet to confirm package type and temperature rating. Ensure compatibility with existing board layouts due to the exposed pad thermal requirement. Cross-reference part numbers carefully as distributor listings may vary in accuracy regarding revision levels.

Selection Notes

Select this component when bidirectional video filtering and buffering are required in a single package. Consider the 16-TSSOP footprint for space-constrained designs. Evaluate the 0.5 dB noise figure against system sensitivity requirements. Confirm that the 15 mA current draw fits within the overall power budget of the target application.

Part Context

This part belongs to the MAX748x family of bidirectional video filters. It shares functional similarities with other members like the MAX7481 but differs in pinout and specific electrical parameters. The series is designed to simplify I/O connections in video systems by combining filtering and buffering functions.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify if upgraded versions or newer generations offer improved specifications while maintaining mechanical compatibility.
