STK4122II
Sample Application Circuit (protection circuit and muting circuit)
Thermal Design
The IC power dissipation of the STK4122II at the IC-operated mode is 22.4W max. at load resistance 8Ω and 31.2W
max. at load resistance 4Ω (simultaneous drive of 2 channels) for continuous sine wave as shown in Figure 1 and 2.
