It is specifically designed to be compatible with the video encoders embedded in Texas Instruments’ OMAP2420 and DaVinci processors or other application processors with 0.5VPP video output. The input common-mode range includes GND, which allows a video-DAC (digital-to-analog converter) to be DC-coupled to the OPA361-Q1. The TV-detection feature simplifies the end-user interface significantly by facilitating the automatic start/stop of video transmission. The output swings within 5mV of GND and 250mV to V+ with a standard back-terminated video load (150Ω). An internal level shift circuit prevents the output from saturating with 0V input, thus...
