TEST AND APPLICATION INFORMATION
Dissipation
Regarding dissipation, distinction must first be made
between static dissipation (independent of frequency) and
dynamic dissipation (proportional to frequency).
The static dissipation of the TDA6101Q is due to high and
low voltage supply currents and load currents in the
feedback network and CRT.
The static dissipation equals:
