STK4162II
Sample Application Circuit (protection circuit and muting circuit)
Thermal Design
The IC power dissipation of the STK4162II at the IC-operated mode is 46W max. at load resistance 8Ω and 81.0W max.
at load resistance 4Ω (simultaneous drive of 2 channels) for continuous sine wave as shown in Figure 1 and 2.
