Description and Introduction

AF Power Amplifier (Split Power Supply) (15W + 15W min, THD = 0.4%) The STK4122 is a hybrid IC (Integrated Circuit) manufactured by Sanyo (now part of ON Semiconductor). It is part of the STK series, which is known for audio amplifier applications. Below are the factual details about the STK4122:  

### **Manufacturer:**  
- **Sanyo Electric Co., Ltd.** (now part of **ON Semiconductor**)  

### **Specifications:**  
- **Type:** Thick Film Hybrid IC (Audio Power Amplifier)  
- **Output Power:** 20W + 20W (stereo, typical at specified conditions)  
- **Supply Voltage Range:** ±25V to ±31V (recommended)  
- **Load Impedance:** 8Ω (typical)  
- **Total Harmonic Distortion (THD):** Low (exact value depends on operating conditions)  
- **Package Type:** SIP (Single In-line Package) with a heat sink tab  
- **Pin Count:** 10 pins  

### **Descriptions:**  
- The STK4122 is designed for stereo audio amplification in consumer electronics such as home stereo systems and compact audio amplifiers.  
- It integrates multiple amplifier stages into a single hybrid module for simplified circuit design.  
- The IC includes built-in thermal and short-circuit protection features.  

### **Features:**  
- **High Power Output:** Capable of delivering 20W per channel (under specified conditions).  
- **Low Noise:** Designed for high-fidelity audio reproduction.  
- **Built-in Protections:** Includes thermal shutdown and overcurrent protection.  
- **Compact Design:** Hybrid construction reduces external component count.  
- **Wide Voltage Range:** Operates efficiently within ±25V to ±31V.
