GENERAL DESCRIPTION
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.
