Description and Introduction

Features of the IMST Hybird ICs The STK4362 is a thick-film hybrid IC (integrated circuit) designed for audio amplifier applications. Below are the factual details about its manufacturer, specifications, descriptions, and features:

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

### **Specifications:**  
- **Type:** Audio Power Amplifier IC  
- **Output Power:**  
  - 20W + 20W (min, at 10% THD, 8Ω, ±25V)  
  - 25W + 25W (max, at 10% THD, 4Ω, ±25V)  
- **Supply Voltage Range:** ±25V (recommended)  
- **Total Harmonic Distortion (THD):** 0.4% (typical, at 1kHz, 10W, 8Ω)  
- **Frequency Response:** 20Hz – 50kHz (±3dB)  
- **Input Impedance:** 55kΩ (typical)  
- **Gain:** 40dB (fixed)  
- **Operating Temperature Range:** -30°C to +75°C  
- **Package Type:** SIP (Single In-line Package) with 15 pins  

### **Description:**  
- The STK4362 is a dual-channel (stereo) audio power amplifier IC designed for high-fidelity sound reproduction.  
- It integrates multiple amplifier stages into a single hybrid module, reducing external component requirements.  
- Suitable for home audio systems, car audio amplifiers, and other medium-power audio applications.  

### **Features:**  
- Built-in muting function to reduce power-on/off noise.  
- Low distortion and wide frequency response for high-quality audio output.  
- Thermal shutdown and overcurrent protection for reliability.  
- Compact SIP package for space-saving PCB design.  
- Requires minimal external components for operation.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Features of the IMST Hybird ICs

Alternative Part Number

  • LM3886TF --: Widely available high-power audio amplifier IC in the same class as the STK4362 hybrid module, with comparable output power and thermal performance, and it is a common modern replacement in audio power stages.
  • TDA7294 --: DMOS audio power amplifier IC offering similar output power and supply voltage range to the STK4362, commonly used as a substitute in audio amplifier repairs.
  • STK4142II --: SANYO thick-film hybrid audio power amplifier from a related STK series with similar pinout and power rating, often used as a drop-in substitute when the exact STK4362 is unavailable.
  • LM3875TF --: Overture-series audio power amplifier providing similar output power and supply range, suitable as a functional substitute for the STK4362.
