POWER DISSIPATION
The total maximum power dissipation of the SAA1064 is made up by the following parts:
1. Maximum dissipation when none of the outputs are programmed (continuous line in Fig.7).
2. Maximum dissipation of each programmed output. The dashed line in Fig.7 visualises the dissipation when all the
3. Maximum dissipation of the programmed segment drivers which can be expressed as:
Under no conditions the total maximum dissipation (500 mW for the SO and 1000 mW for the DIL package) should be
exceeded.

segments are programmed (max. 16 in the static, and max. 32 in the dynamic mode). When less segments are
programmed one should take a proportional part of the maximum value.
