ADA4417-3ARMZ

Overview

The ADA4417-3 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, offering 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 pin-selectable DC offset control and a low-power disable mode drawing 10 μA typical current.

Feature Summary

• Integrates three sixth-order Butterworth filters optimized for high-definition video signal processing.
• Features pin-selectable output DC offset control to prevent sync tips from hitting the ground rail.
• Includes a dedicated disable function that significantly reduces power consumption when inactive.
• Provides rail-to-rail output capability suitable for direct driving of terminated loads.

Applications

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

Procurement Notes

Verify the specific ordering suffix (e.g., ARMZ, ARMZ-R7) to confirm package type and reel quantity requirements. Ensure the selected variant matches the required RoHS compliance status. Confirm the operating temperature range aligns with system specifications before procurement.

Selection Notes

Select this component for applications requiring compact integration of triple-channel video filtering. The fixed ×2 gain and high input impedance simplify circuit design by eliminating external buffer stages. Consider the disable feature for portable devices where power conservation during idle states is critical.

Part Context

FAQ

How does the DCO pin affect the output voltage?

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 offset.

What is the purpose of the DISABLE pin?

The DISABLE pin allows the device to enter a low-power state. Pulling it to ground reduces the supply current to typically 10 μA, conserving power when the filter is not in use.
