Description

The OPA362 high-speed amplifier is optimized for 3V portable video applications. It is specifically designed to be compatible with the video encoders embedded in Texas Instruments’ OMAP3430 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 OPA362. 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 preventing sync-pulse clipping in common video circuits. Therefore, the OPA362 is ideally suited for dc-coupling to the video load.

The OPA362 has been optimized for space-sensitive applications by integrating internal gain setting resistors (G = 5.2V/V) and a two-pole video-DAC reconstruction filter.

In shutdown mode, quiescent current is reduced to less than 1.5µA, dramatically reducing power consumption and prolonging battery life.

The OPA362 is available in the tiny 2mm × 2.1mm SC70-6 package.
