DESCRIPTION
The OPA360 high-speed amplifier is optimized for 3V
portable video applications. It has been specifically
designed to be compatible with digital-to-analog
converters (DACs) embedded in video processors, such
as Texas Instruments’ family of Digital Media Processors
and others. The input common-mode range includes
GND, which allows the Video-DAC to be DC-coupled to
the OPA360.
The output swings within 25mV of GND and 300mV 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 OPA360
is ideally suited for DC-coupling to the video load. If
AC-coupling is preferred, the OPA360 offers a
sag-correction feature that significantly reduces the size of
the output coupling capacitor.
The OPA360 has been optimized for space-sensitive
applications by integrating sag-correction, internal gain
setting resistors (G = 2), and a 2-pole video-DAC
reconstruction filter.
In shutdown mode, the quiescent current is reduced to
< 5µA, dramatically reducing power consumption and
prolonging battery life.
The OPA360 is available in the tiny 2mm x 2.1mm SC70-6
package.

(1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those specified is not implied.
(2) Input terminals are diode-clamped to the power-supply rails.
Input signals that can swing more than 0.5V beyond the supply
rails should be current-limited to 10mA or less.
(3) Short-circuit to ground, one amplifier per package.
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
