GENERAL DESCRIPTION
The ADA4431-1 is a fully integrated video reconstruction filter
that combines excellent video specifications with low power
consumption, making it ideal for portable video filtering
applications. The ADA4431-1 is able to detect whether a video
load is present at the output, powering down the device when
the load is disconnected.
The ADA4431-1 operates on single supplies as low as 2.5 V
while providing the dynamic range required by the most
demanding video systems. The on-board charge pump
provides a virtual negative supply, allowing the video signal to
be dc-coupled and the black level to be set to ground, while the
sync passes cleanly at 300 mV below ground.
When operating with the charge pump off, the ADA4431-1
provides a dc offset to keep the sync tip approximately 100 mV
above ground. In addition, the part features SAG correction,
which permits the use of smaller capacitors in applications with
ac-coupled outputs.
The ADA4431-1 is packaged in a low profile 16-lead LFCSP and
operates in the industrial temperature range of 40°C to +85°C.
