STK4192II
Sample Application Circuit (protection circuit and muting circuit)
Thermal Design
The IC power dissipation of the STK4192II at the IC-operated mode is 66W max. at load resistance 8Ω and 103W max.
at load resistance 4Ω (simultaneous drive of 2 channels) for continuous sine wave as shown in Figure 1 and 2.
