Overview
The OPA361AIDCKT is a high-speed video amplifier designed by Texas Instruments, optimized for 3V portable video applications. It is specifically compatible with the video encoders embedded in Texas Instruments OMAP2420 and DaVinci processors, or other application processors with 0.5V PP video output. The amplifier features an internal gain setting, a 2-pole video-DAC reconstruction filter, and an integrated level shift circuit, making it ideal for DC-coupling to video loads. Its compact SC70-6 package (2.0mm x 2.1mm) and low power consumption make it suitable for space-sensitive and battery-powered devices.
