Description and Introduction

AF Power Amplifier (5W + 5W min, THD = 1.0%) The STK4332 is a hybrid IC (integrated circuit) manufactured by SANYO. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Type:** Hybrid IC (Thick Film)  
- **Function:** Audio Power Amplifier  
- **Output Power:**  
  - 15W + 15W (min) at 8Ω, ±20V supply  
  - 20W + 20W (min) at 4Ω, ±18V supply  
- **Supply Voltage Range:** ±13V to ±20V  
- **Total Harmonic Distortion (THD):** 0.3% (typical) at 1kHz, 8Ω, 15W  
- **Frequency Response:** 20Hz to 50kHz (±1dB)  
- **Input Impedance:** 55kΩ (typical)  
- **Gain:** 40dB (typical)  
- **Operating Temperature Range:** -30°C to +75°C  
- **Package:** SIP (Single In-line Package), 10-pin  

### **Descriptions:**  
The STK4332 is a stereo power amplifier IC designed for high-fidelity audio applications. It integrates two amplifier channels in a single package, making it suitable for stereo systems. The thick-film hybrid construction ensures reliability and thermal stability.  

### **Features:**  
- **Dual-Channel Amplifier:** Supports stereo output.  
- **Low Noise & Distortion:** Ensures high-quality audio reproduction.  
- **Built-in Thermal Protection:** Prevents overheating damage.  
- **Simple External Circuitry:** Requires minimal external components for operation.  
- **Wide Supply Voltage Range:** Allows flexibility in power supply design.  

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

Application Scenarios & Design Considerations

AF Power Amplifier (5W + 5W min, THD = 1.0%)

Alternative Part Number

  • STK433-130 --: Same Sanyo/ON Semiconductor thick-film hybrid audio amplifier family with comparable output power and pinout, widely used as a direct substitute for STK4332 in audio power stages.
  • TDA7265 --: Class AB stereo audio power amplifier with similar supply voltage and output power range, commonly used as a functional replacement when the STK hybrid is unavailable.
  • LM4766 --: Dual audio power amplifier IC offering comparable output power and voltage ratings, suitable as an alternative design choice for the same audio amplifier application.
