Description and Introduction

Function class AB 2 channels AF power amplifier The STK442-090 is a hybrid IC (Integrated Circuit) manufactured by Sanyo (now part of ON Semiconductor). It is a thick-film hybrid power amplifier designed for audio applications.  

### **Specifications:**  
- **Type:** Thick-film hybrid IC  
- **Function:** Power amplifier  
- **Output Power:** 30W per channel (typical at 8Ω, THD = 10%)  
- **Supply Voltage Range:** ±25V to ±35V  
- **Total Harmonic Distortion (THD):** Typically 0.08% (at 1kHz, 20W, 8Ω)  
- **Frequency Response:** 20Hz to 50kHz (-3dB)  
- **Input Impedance:** 30kΩ  
- **Package Type:** SIP (Single In-line Package)  
- **Pin Count:** 10 pins  

### **Descriptions and Features:**  
- Designed for high-fidelity stereo audio amplification.  
- Includes built-in thermal protection and overcurrent protection.  
- Low noise and distortion for improved sound quality.  
- Suitable for use in home audio systems, amplifiers, and other audio equipment.  
- Requires external heat sink for proper thermal management.  
- Compatible with standard amplifier circuit designs.  

This IC is commonly used in audio amplifiers due to its reliability and performance characteristics.

Description and Introduction

Function class AB 2 channels AF power amplifier The STK442-090 is a hybrid IC (integrated circuit) manufactured by SANYO. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** SANYO  
- **Type:** Hybrid IC (Thick Film Hybrid IC)  
- **Function:** Audio Power Amplifier  
- **Package:** SIP (Single In-line Package)  
- **Number of Channels:** 2 (Stereo)  
- **Output Power:** 20W per channel (typical at specified conditions)  
- **Operating Voltage:** Typically ±25V to ±30V (dual power supply)  
- **Total Harmonic Distortion (THD):** Low distortion for high-fidelity audio  
- **Frequency Response:** Suitable for audio applications (typically 20Hz–20kHz)  
- **Thermal Protection:** Includes built-in thermal shutdown  

### **Descriptions:**
The STK442-090 is a power amplifier IC designed for stereo audio applications. It integrates multiple amplifier stages into a single SIP package, reducing external component count. It is commonly used in audio systems such as amplifiers, home stereos, and other consumer electronics requiring moderate power output with good sound quality.

### **Features:**
- **High Power Output:** Capable of delivering up to 20W per channel.  
- **Low Noise & Distortion:** Designed for high-fidelity audio reproduction.  
- **Built-in Protection:** Includes thermal shutdown to prevent overheating.  
- **Compact Design:** SIP package allows space-efficient PCB mounting.  
- **Wide Supply Voltage Range:** Supports typical dual-supply operation (±25V to ±30V).  

This information is based on the manufacturer's datasheet and technical documentation. For exact performance parameters, always refer to the official datasheet.
