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 (150). 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.
