High speed op amp with filter
ON Semiconductor Corp
Description
The NCS2561 is a single high speed video driver including a 2-pole reconstruction filter and SAG-correction capability. The NCS2561 is available in a space-saving SC-88 package optimized for low voltage, portable applications. It is designed to be compatible with the Digital-to-Analog (DAC) embedded in most video processors. The NCS2561 internally integrates an 8-MHz 2-pole video DAC reconstruction filter with a fixed gain of 2. The NCS2561 also has a built in SAG-correction circuit when used at the output in an AC-coupled mode. To further reduce power consumption, an enable pin is provided.
