ADA4430-1YKSZ

The ADA4430-1YKSZ from Analog Devices is an integrated video reconstruction filter and line driver, combining a 6th-order low-pass filter with a rail-to-rail output amplifier optimized for single-supply operation. The device delivers high-quality signal conditioning by removing out-of-band noise and DAC aliasing artifacts while driving standard video loads directly. Its low quiescent current and compact SC-70 package enable space-constrained designs, and the internal filter provides a sharp roll-off characteristic with consistent group delay for composite video bandwidths. The rail-to-rail output stage supports AC-coupled or DC-coupled drive into 75 Ω reversed-terminated lines without clipping, even at supply voltages as low as 2.7 V.

Typical applications include portable media players, digital still cameras, camcorders, and handheld gaming systems where the device reconstructs CVBS or S-video signals from DAC outputs. It also serves embedded industrial cameras, video surveillance modules, and automotive driver-assistance imagery where board space and power budgets are limited. In these systems the ADA4430-1YKSZ replaces discrete passive filter networks and external line drivers, reducing component count and improving signal integrity. From a procurement standpoint, this part is manufactured on a standard industrial grade flow and is supplied in tape-and-reel format. While no special military or high-reliability suffix applies, designers should verify temperature range and end-of-life status through distribution channels, as Analog Devices’ standard product lifecycle management applies. The miniature SC-70 footprint and low-power architecture make it well-suited for long-life embedded vision products where consistent analog performance and supply continuity are critical.
