ADA4430-1YKSZ-R7

Overview

The ADA4430-1YKSZ-R7 is a fully integrated video reconstruction filter designed for portable applications. It delivers sixth-order low-pass filtering with 1 dB flatness out to 8 MHz and 50 dB rejection at 27 MHz. The device operates on single supplies ranging from 2.5 V to 6 V, consuming 1.85 mA typical quiescent current. It features an ultralow power-down current of 0.1 μA via the disable pin. Key specifications include 0.25% differential gain, 0.10° differential phase, and rail-to-rail output capability.

Feature Summary

• Provides sixth-order low-pass filtering performance suitable for SD video standards like NTSC and PAL.
• Features SAG correction functionality that enables the use of smaller capacitors in AC-coupled output configurations.
• Includes a dedicated disable input that reduces supply current to less than 0.1 μA when inactive.
• Offers high input-to-output isolation exceeding 90 dB in the disabled state.

Applications

• Portable media players
• Portable gaming consoles
• Cell phones
• Digital still cameras
• Portable DVD players

Procurement Notes

Verify the specific ordering suffix R7 corresponds to the required reel quantity of 3,000 units. Confirm the KS-6 package option matches the PCB footprint requirements. Ensure the component meets RoHS compliance standards as indicated by the Z suffix. Cross-reference the temperature range against the operational environment constraints.

Selection Notes

Select this component for designs requiring high-order filtering within a minimal footprint. The SC70 package is exclusive to commercial grade variants, distinguishing it from automotive options. Evaluate the 2.5 V to 6 V supply range compatibility with existing system rails. Consider the low quiescent current for battery-operated devices where power efficiency is critical.

Part Context

This part belongs to the ADA4430-1 family of ultralow power video filters. The YKSZ designation identifies the commercial grade version housed in a 6-Lead SC70 package. It differs from the W-series which utilizes a SOT-23 package and holds automotive qualification. The device integrates a video reconstruction filter with a driver stage.

Replacement Considerations

ADA4430-1YKSZ-R2 offers the same electrical characteristics in a tape-and-reel format of 250 units. ADA4430-1YKSZ-RL provides the identical component in a larger 10,000-unit reel configuration. Both alternatives maintain the SC70 package and commercial temperature rating.
