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.
