ADA4424-6ARUZ-RL

Overview

The ADA4424-6ARUZ-RL is a six-channel video reconstruction filter with an integrated charge pump, manufactured by Analog Devices Inc. It operates from single 3.3 V and 5 V supplies within the industrial temperature range of −40°C to +85°C. The device features three SD channels with a typical 1 dB bandwidth of 18 MHz and three ED/HD channels with selectable corner frequencies of 25 MHz or 34 MHz/39 MHz. It provides a fixed gain of 6.2 dB (2.042 V/V) and includes internal Y/C summation for CVBS output. The on-board charge pump generates a negative rail, enabling rail-to-rail outputs without external coupling capacitors. Packaged in a 38-lead TSSOP, it supports D-terminal and S-terminal signaling.

Feature Summary

• Integrates a charge pump to generate a negative supply rail, eliminating the need for large output coupling capacitors.
• Features flexible DC offset cancellation for luma channels with four distinct detection modes.
• Supports D-terminal and S-terminal signaling with dedicated control inputs and outputs.
• Provides separate power-down pins for independent control of SD and ED/HD sections.

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The -RL suffix indicates a reel package containing 2,500 units. Ensure compatibility with the required surface-mount assembly process for the 38-lead TSSOP package. Confirm RoHS compliance status as indicated by the Z suffix in the base part number.

Selection Notes

Select this component when designing systems requiring simultaneous processing of SD and HD video signals. The integrated charge pump simplifies board layout by removing external negative voltage generation requirements. Consider the available DC offset cancellation modes if precise signal alignment is critical. Verify that the 75 Ω driving capability meets the load requirements of the downstream video stages.

Part Context

This part belongs to the ADA4424-6 series of video filters. It is specifically designed for consumer electronics applications handling standard definition and high definition video formats. The device consolidates multiple filter functions into a single IC, reducing component count compared to discrete solutions.
