Description and Introduction

Features of the IMST Hybird ICs The STK4372 is a thick-film hybrid IC (integrated circuit) manufactured by SANYO. Below are the factual specifications, descriptions, and features based on the available knowledge base:

### **Specifications:**  
- **Manufacturer:** SANYO  
- **Type:** Thick-film hybrid IC (audio amplifier)  
- **Output Power:** 15W per channel (typical at 8Ω, THD = 10%)  
- **Supply Voltage Range:** ±12V to ±25V (recommended)  
- **Total Harmonic Distortion (THD):** 0.4% (typical at 1kHz, 8Ω, 10W)  
- **Frequency Response:** 20Hz - 50kHz (±3dB)  
- **Input Impedance:** 30kΩ (typical)  
- **Gain:** 30dB (typical)  
- **Package Type:** SIP (Single In-line Package)  
- **Pin Count:** 15 pins  

### **Descriptions:**  
- The STK4372 is a stereo power amplifier IC designed for audio applications.  
- It integrates two amplifier channels in a single package, making it suitable for compact stereo systems.  
- The thick-film hybrid construction ensures reliability and thermal stability.  

### **Features:**  
- **Built-in thermal protection** to prevent overheating.  
- **Low noise and low distortion** for high-quality audio output.  
- **Simple external circuitry** due to integrated design.  
- **Wide operating voltage range** allows flexibility in power supply design.  

For exact application details, always refer to the official SANYO datasheet.
