ADA4424-6ARUZ-R7

Overview

The ADA4424-6ARUZ-R7 is a six-channel video reconstruction filter designed for consumer applications, featuring three standard definition (SD) channels and three extended/high definition (ED/HD) channels. It operates from a single 3.3 V supply with a dedicated 5 V pin for D/S terminal signaling. The device provides a fixed gain of 6.2 dB and includes an internal charge pump to generate a negative rail, enabling dc-coupled outputs without external capacitors. SD channels offer a typical 18 MHz bandwidth, while ED/HD channels provide selectable corner frequencies of 25 MHz or 39 MHz/34 MHz. It supports Y/C summation for CVBS output and flexible input dc offset cancellation.

Feature Summary

• Integrates on-chip charge pump to create a negative supply rail, eliminating the need for large output coupling capacitors.
• Supports D-terminal and S-terminal signaling with configurable aspect ratio and scan type outputs.
• Features four distinct modes for detecting and cancelling dc input offsets on luma channels.
• Includes separate enable pins to independently power down SD and ED/HD sections.

Applications

• DVD players and recorders
• Set-top boxes
• Projectors
• Personal video recorders

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the component meets all required environmental standards and RoHS compliance specifications before integration into production designs.

Selection Notes

Select this component when designing systems requiring integrated video filtering with minimal external passive components. Ensure the design accommodates the 38-lead TSSOP package dimensions and thermal requirements. Verify that the application utilizes compatible signal levels and does not exceed the absolute maximum ratings for supply voltages.

Part Context
