Frequency Response Flatness at Various Power Supplies Portable DVD players Portable video cameras GENERAL DESCRIPTION The ADA4430-1 is a fully integrated video reconstruction filter The ADA4430-1 also provides an on-chip dc offset to avoid that combines excellent video specifications with low power clipping of the sync tips at the filter output, as well as SAG consumption and an ultralow power disable, making it ideal correction that permits smaller capacitor values to be used in for portable video filtering applications. With 1 dB frequency applications with ac-coupled outputs. flatness out to 8 MHz and 50 dB rejection at 27 MHz, the The ADA4430-1 is available in a two 6-lead packages. The SC70 ADA4430-1 is ideal in SD video applications, including for commercial applications and the SOT-23 for automotive NTSC and PAL. applications are rated to work in the extended temperature The ADA4430-1 operates on single supplies as low as 2.5 V and range of 40C to +125C. as high as 6 V while providing the dynamic range required by the most demanding video systems.
