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
0.5V_PP 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.
