DESCRIPTION
The OPA361 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’ 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. 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 OPA361
is ideally suited for DC-coupling to the video load.
The OPA361 has been optimized for space-sensitive
applications by integrating internal gain setting resistors
G = 5.2V/V) and a 2-pole video-DAC reconstruction filter.
In shutdown mode, the quiescent current is reduced to
< 1.5μA, dramatically reducing power consumption and
prolonging battery life.
The OPA361 is available in the tiny 2mm x 2.1mm SC70-6
package.
