ADA4417-3ARMZ-R7

Overview

The ADA4417-3ARMZ-R7 is a fully integrated triple video reconstruction filter designed for high-definition video applications. It features three independent sixth-order Butterworth filters with a -1 dB bandwidth of 38 MHz and 44 dB rejection at 75 MHz. The device operates on a single 3.3 V to 5 V supply, providing rail-to-rail outputs with a fixed throughput gain of ×2. Key performance metrics include 0.06% differential gain, 0.21° differential phase, and 5 ns group delay variation. It includes a pin-selectable output DC offset function and a disable feature that reduces quiescent current to 10 μA.

Feature Summary

• Integrates three independent sixth-order Butterworth filters optimized for high-definition video signal processing.
• Features a pin-selectable output DC offset control to manage signal levels relative to the ground rail.
• Includes a low-power disable mode that significantly reduces supply current when the device is inactive.
• Provides rail-to-rail output capability suitable for efficient operation on lower voltage single-supply systems.

Applications

• Set-top boxes
• HDTVs
• Projectors
• DVD players/recorders
• Personal video recorders

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and quantity specifications. Confirm RoHS compliance status as indicated in the ordering guide. Ensure the selected variant matches the required temperature range and package type for your design constraints.

Selection Notes

Select this component for designs requiring integrated filtering and driving capabilities for HD video signals. Consider the single-supply voltage range and power consumption requirements, particularly if utilizing the disable feature for battery-operated devices. Evaluate the need for DC offset adjustment based on downstream input requirements.

Part Context

This part belongs to the ADA4417 family of integrated video filters from Analog Devices. It is specifically engineered to replace discrete filter solutions in consumer electronics, offering a compact footprint and reduced bill of materials by combining filtering, buffering, and driving functions in a single 10-lead MSOP package.

FAQ

How does the DCO pin affect the output signal?

When the DCO pin is tied to VCC, the output video signal is offset by 200 mV. When tied to ground, the output DC level follows the input level without additional offset.

What is the purpose of the DISABLE pin?

The DISABLE pin allows the device to be powered down to conserve energy. Asserting this pin (pulling it to ground) reduces the typical supply current to 10 μA.
