Power Down Characteristics
The LM1212 includes a built-in power down spot killer to
prevent a flash on the screen upon power down. The
LM1212’s output voltage decreases as the device is being
powered down, thus preventing a flash on the screen. In
some preamplifiers, 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 caus-
ing 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 possi-
ble is recommended. For suggestions on optimum PC board
layout, please see the reference section below.
