Description and Introduction

AF Power Amplifier (Split Power Supply) (45W + 45W min, THD = 0.4%) The STK4182 is a hybrid IC (Integrated Circuit) manufactured by Sanyo (now part of ON Semiconductor). It is a thick-film audio power amplifier module designed for use in stereo audio applications.  

### **Specifications:**  
- **Type:** Stereo Audio Power Amplifier (Hybrid IC)  
- **Output Power:** 20W per channel (at 8Ω, THD = 10%)  
- **Supply Voltage Range:** ±25V (recommended)  
- **Total Harmonic Distortion (THD):** 0.4% (typical)  
- **Frequency Response:** 20Hz – 50kHz (±3dB)  
- **Input Impedance:** 33kΩ  
- **Package Type:** SIP (Single In-line Package)  
- **Pin Count:** 10 pins  

### **Descriptions & Features:**  
- **Hybrid Design:** Combines thick-film resistors and discrete semiconductor components for high reliability.  
- **Built-in Thermal Protection:** Prevents overheating damage.  
- **Low Noise & Distortion:** Suitable for high-fidelity audio applications.  
- **Mute Function:** Includes a built-in muting circuit for pop-free operation.
