ADA4412-3ARQZ-RL

Overview

The ADA4412-3ARQZ-RL is an integrated triple video filter with selectable cutoff frequencies for RGB, HD/SD signals. It features sixth-order adjustable filters at 36 MHz, 18 MHz, and 9 MHz. The device operates on a single +5 V or ±5 V supply, drawing 53 mA to 60 mA quiescent current. It includes a disable feature reducing current to 10 μA. Outputs swing rail-to-rail, supporting 4.5 V p-p on a single 5 V supply. DC output offset is adjustable by ±0.5 V input-referred. Fixed throughput gain is ×2. It supports NTSC standards with differential gain of 0.16% and phase of 0.05 degrees.

Feature Summary

• Integrated triple sixth-order video filters with selectable bandwidths for component video standards
• Rail-to-rail output buffers capable of driving dual 75 Ω loads in AC or DC coupled configurations
• Differential DC offset control allowing continuous adjustment over an input-referred range of ±500 mV
• Power-down capability via the DISABLE pin to minimize supply current consumption

Applications

• Video reconstruction filtering following DAC outputs in encoders
• Antialias filtering for high-definition video signal processing
• Set-top boxes and personal video recorders
• DVD players and HDTVs

Procurement Notes

Verify the specific ordering suffix corresponds to the required reel quantity configuration. Confirm that the package type matches the design footprint requirements. Ensure the temperature range aligns with the operational environment specifications. Check for lead-free compliance status if required by regulatory standards. Validate the revision level against the latest datasheet documentation.

Selection Notes

Select this component when designing circuits requiring integrated filtering and buffering for RGB or YPbPr signals. Consider the fixed ×2 gain and rail-to-rail output capabilities for direct drive applications. Evaluate the power supply constraints, as the device supports both single and dual supply architectures. Assess the need for DC offset adjustment to accommodate specific voltage levels in the signal chain.
