EXCELLENT VIDEO PERFORMANCE
INTERNAL GAIN: 5.2V/V
The OPA362 high-speed amplifier is optimized for 3V
portable video applications. It is specifically designed

end-user interface significantly by facilitating the
automatic start/stop of video transmission.

LOW QUIESCENT CURRENT: 4.3mA
output from saturating with 0V input, thus preventing
