Description and Introduction

Thick Film Hybrid IC(2 Power 2 Channel 10 to 30 W, AF Power AMP) The STK457 is a hybrid IC (Integrated Circuit) manufactured by Sanyo (now part of ON Semiconductor). It is designed for use in audio amplifier applications, particularly in stereo systems.  

### **Specifications:**  
- **Type:** Hybrid IC (Thick Film)  
- **Function:** Dual-channel (Stereo) Audio Power Amplifier  
- **Output Power:** Typically 15W per channel (at 8Ω, THD = 10%)  
- **Supply Voltage Range:** ±12V to ±25V (Dual Supply)  
- **Total Harmonic Distortion (THD):** Low distortion for improved audio quality  
- **Package:** SIP (Single In-line Package) with heat sink mounting  

### **Descriptions and Features:**  
- **Dual-Channel Operation:** Supports stereo amplification.  
- **Built-in Thermal Protection:** Prevents overheating.  
- **Low Noise:** Designed for high-fidelity audio applications.  
- **Wide Supply Voltage Range:** Allows flexibility in power supply design.  
- **Compact Design:** Suitable for space-constrained audio systems.  

The STK457 is commonly used in home audio amplifiers, stereo receivers, and other audio equipment requiring moderate power output.

Application Scenarios & Design Considerations

Thick Film Hybrid IC(2 Power 2 Channel 10 to 30 W, AF Power AMP)

Alternative Part Number

  • STK404-130 --: Similar audio power amplifier module in the STK series with comparable output power and supply voltage, often used as a substitute in audio equipment.
  • STK4050II --: Higher-power STK hybrid audio amplifier module with similar pinout and application, suitable when slightly higher output capability is acceptable.
  • LM3886TF --: Discrete IC audio power amplifier offering comparable output power and performance, usable as a functional replacement with minor circuit adaptation.
