Description and Introduction

2ch./1packge, +- Power Supply Built-in Muting Circuit 25W/ch. ~ 70W/ch. THD=0.02% The STK4191X is a hybrid IC (Integrated Circuit) manufactured by SANYO. Below are the factual specifications, descriptions, and features based on available information:

### **Specifications:**  
- **Type:** Hybrid IC (Thick Film)  
- **Function:** Audio Power Amplifier  
- **Output Power:** 30W (per channel, typical at 8Ω, THD = 0.08%)  
- **Operating Voltage (VCC):** ±25V to ±31V (recommended)  
- **Total Harmonic Distortion (THD):** 0.08% (typical at 1kHz, 30W)  
- **Frequency Response:** 20Hz - 50kHz (-3dB)  
- **Input Impedance:** 55kΩ  
- **Gain:** 40dB (fixed)  
- **Package:** SIP (Single In-line Package)  
- **Pin Count:** 10 pins  
- **Thermal Resistance (Junction-to-Case):** 2.5°C/W  

### **Descriptions:**  
- The STK4191X is a stereo power amplifier IC designed for high-fidelity audio applications.  
- It incorporates built-in thermal shutdown and overcurrent protection circuits.  
- The thick-film hybrid construction ensures reliability and durability.  

### **Features:**  
- **High Output Power:** Capable of delivering 30W per channel (8Ω load).  
- **Low Distortion:** THD as low as 0.08% for clear audio reproduction.  
- **Wide Frequency Response:** Supports a broad audio range (20Hz - 50kHz).  
- **Built-in Protections:** Includes thermal shutdown and overcurrent protection.  
- **Compact Design:** SIP package allows for space-efficient PCB mounting.  

This information is based on SANYO's official documentation for the STK4191X. For detailed application notes, refer to the datasheet.
