The is an audio power amplifier IC for multichannel speaker applications. It comprises two 25W channels (left and right) and a 50W channel (center) in a single package. It is fully pin compatible with the 3-channel output devices (STK400-×00 series) and 2-channel output devices (STK401-×00 series). In addition, it supports 6/3 output load impedance.
Pin compatible with the 3-channel output devices (STK400-×00 series) and 2-channel output devices (STK401-×00 series) Output load impedance RL=6/3 supported Pin configuration grouped into individual blocks of inputs, outputs and supply lines to minimize the adverse effects of pattern layout on operating characteristics.

Note. All tests are measured using a constant-voltage supply unless otherwise specified. Available time for load short-circuit and output noise voltage are measured using the transformer supply specified below. The output noise voltage is the peak value of an average-reading meter with an rms value scale (VTVM). A regulated AC supply (50Hz) should be used to eliminate the effects of AC primary line flicker noise.
