Schematic
Description
Video inputs. These inputs
must
be AC
coupled with a 4.7 nF cap. DC restoration is
done at these inputs. A series resistor of
about 33
and external ESD protection
diodes should also be used for ESD
protection.

Analog Ground
Ground Pin for the analog circuits of the
LM1262.
Power supply pin for LM1262.
Sets the internal current sources through a
10 k
1% external resistor. Resistor value
and accuracy is critical for optimum
operation of the LM1262.

SDA
The I
2
C data line. A pull-up resistor of about
2 k
should be connected between this pin
and +5V. A 300
resistor should be
connected in series with the data line for
protection against arcing.

SCL
The I
2
C Clock line. A pull-up resistor of
about 2 k
should be connected between
this pin and +5V. A 300
resistor should be
connected in series with the clock line for
protection against arcing.

DAC2
DAC1
DAC outputs for cathode cut-off adjustments
and brightness control. DAC 4 can be set to
change the outputs of the other three DACs,
acting as the brightness control. The DACs
are set through the I
2
C bus.

Digital Ground
Ground Pin for the digital circuits of the
LM1262.
