5 - TYPICAL APPLICATION
BASIC electronically tuned TV system.
6 - POWER DISSIPATION OF THE IC
The power dissipation of the IC can be limited us-
ing different configurations.
In this application R must be chosen by taking into
account the worst operating conditions.
R is determined by the maximum number of seg-
ments activated.
The worst case condition for the device is when
roughly half of the maximum number of segments
are activated.
It must be checked that the total power dissipation
does not exceed the absolute maximum ratings of
the device.
In critical cases more resistors can be used in con-
junction with groups of segments. In this case the
current variation in the single resistor is reduced
and P
tot
limited.
