STK 4192 Power Amplifier Circuit
Features
AF Power Amplifier (Split Power Supply)
(50W + 50W min, THD = 0.4%)
• The STK4102II series (STK4192II) and STK4101V
series (high-grade type) are pin-compatible in the output
range of 6W to 50W and enable easy design.
• Small-sized package whose pin assignment is the same
as that of the STK4101II series
• Built-in muting circuit to cut off various kinds of pop
noise
• Greatly reduced heat sink due to substrate temperature
125°C guaranteed
• Excellent cost performance
