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 two 6-lead packages. The SC70

for commercial applications and the SOT-23 for automotive

applications are rated to work in the extended temperature

range of −40°C to +125°C.
