Power Down Characteristics
The LM2202 includes a built-in power down spot killer to pre-
vent a flash on the screen upon power down. The LM2202’s
output voltage decreases as the device is being powered
down, thus preventing a flash on the screen. In some pream-
plifiers, the video output signal may go high as the device is
being powered down. This may cause a whiter-than-white
level at the output of the CRT driver, thus causing a flash on
the screen.
PC Board Layout Considerations
For
optimum
performance
and
stable
operation,
a
double-sided printed circuit board with adequate ground
plane and power supply decoupling as close to the V
CC pins
as possible is recommended. For suggestions on optimum
PC board layout, please see the reference section below.
