FEATURES  
DESCRIPTION  
23  
•
EXCELLENT VIDEO PERFORMANCE  
•
INTERNAL GAIN: 5.2V/V  
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  
•
•
SUPPORTS TV-DETECTION  
COMPATIBLE WITH OMAP343x and DaVINCI™  
PROCESSORS  
•
•
TWO-POLE RECONSTRUCTION FILTER  
INPUT RANGE INCLUDES GROUND  
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.

DC-Coupled Output(1)  
No Output Capacitors Needed  
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.

RAIL-TO-RAIL OUTPUT  
LOW QUIESCENT CURRENT: 4.3mA  
SHUTDOWN CURRENT: 1.5μA  
SINGLE-SUPPLY: 2.5V to 3.3V  
SC70-6 PACKAGE: 2.0mm x 2.1mm  
RoHS COMPLIANT  
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.  
•
(1)  
Internal circuitry avoids output saturation, even with 0V sync  
tip level at the input video signal.  
In shutdown mode, quiescent current is reduced to  
less than 1.5μA, dramatically reducing power  
consumption and prolonging battery life.
