3V Video Amplifier
DESCRIPTION
The OPA360 high-speed amplifier is optimized for 3V
portable video applications. It has been specifically
designed
to
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
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.

    ... To achieve good performance, a 22µF sag correction and 47µF coupling capacitor can be used. Figure 10 and Figure 11 show comparisons for a standard video circuit with a 220µF coupling capacitor and the OPA360 with sag correction. Figure 10 shows that the 22µF/47µF combination leads to only a slightly greater tilt in the 50Hz, 1/2 black − ...
