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