This is Thick Film Hybrid IC. STK4152II is AF Power Amplifier (Split Power Supply). (30W + 30W min, THD = 0.4%).

An AF (Audio Frequency) power amplifier is an electronic circuit that amplifies low-frequency audio signals to drive speakers or headphones. The primary purpose of an AF power amplifier is to boost the audio signal’s power level to a sufficient level to produce audible sound through the connected output device, such as speakers.



• The STK4102II series (STK4152II) 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 [ … ]
