STK4102II

No. 2324—7/8

Sample Application Circuit (II) (protection circuit and muting circuit)

Thermal Design

The IC power dissipation of the STK4102II at the IC-operated mode is 9.8W max. at load resistance 8

Ω and 15.5W max.

at load resistance 4

Ω (simultaneous drive of 2 channels) for continuous sine wave as shown in Figure 1 and 2.

Output power, Po - W

In an actual application where a music signal is used, it is impractical to estimate the power dissipation based on the con-

tinuous signal as shown above, because too large a heat sink must be used. It is reasonable to estimate the power dissipa-

tion as 1/10 Po max. (EIAJ).
