ADA4417-3ARMZ-RL

Overview

The ADA4417-3ARMZ-RL 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 a fixed throughput gain of ×2 and rail-to-rail output capabilities. It includes pin-selectable DC offset control and a low-power disable feature that reduces quiescent current to 10 μA. Packaged in a compact 10-lead MSOP, it supports operation from -40°C to +85°C.

Feature Summary

• Integrated triple-channel sixth-order Butterworth filtering optimized for HD video signal reconstruction
• Pin-selectable output DC offset control to prevent sync tip clipping against the ground rail
• Low-power disable mode significantly reduces supply current when the device is inactive
• Rail-to-rail output drivers capable of driving dual 75 Ω terminated loads

Applications

• Set-top boxes
• High-definition televisions (HDTVs)
• Video projectors
• DVD players and recorders
• Personal video recorders

Procurement Notes

Verify the specific ordering suffix RL indicates a reel quantity of 2,500 units as documented in the Analog Devices ordering guide. Confirm RoHS compliance status associated with the Z suffix. Ensure the procurement channel provides valid traceability for the H0Q branding code. Cross-reference the package option RM-10 to match the 10-lead MSOP physical dimensions required for the design.

Selection Notes

Select this component when designing video reconstruction stages requiring third-order or higher filtering characteristics within a single package. The fixed ×2 gain simplifies circuit topology by eliminating external feedback resistors. Consider the pin-selectable DC offset feature if the downstream ADC requires a specific input voltage range to avoid ground rail saturation. Evaluate the disable pin functionality for systems requiring active power management during idle states.

Part Context

This part belongs to the ADA4417-3 family of integrated video filters manufactured by Analog Devices. It is specifically engineered to replace discrete passive and active filter components in consumer electronics. The device consolidates filtering, buffering, and level-shifting functions into a single surface-mount package, reducing board space and assembly complexity for high-definition video signal paths.

FAQ

How does the DCO pin affect the output DC level?

When the DCO pin is tied to VCC, the output signal is offset by 200 mV to prevent sync tips from hitting the ground rail. When tied to ground, the output DC level follows the input level without additional offset.

What is the power consumption when the device is disabled?

When the DISABLE pin is pulled to ground, the device enters a low-power state with a typical quiescent current of 10 μA.

Can the outputs drive multiple loads simultaneously?

Yes, each output buffer can drive two ac- or dc-coupled 75 Ω source-terminated loads directly.
