Description and Introduction

PNP NPN Darlington H-bridge The STA474A is a power amplifier IC manufactured by SanKen. Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Digital Power Amplifier IC  
- **Output Power:** 50W × 2 channels (stereo)  
- **Supply Voltage (VCC):** ±12V to ±25V  
- **Operating Voltage Range:** ±12V to ±25V  
- **Total Harmonic Distortion (THD):** 0.03% (typical)  
- **Signal-to-Noise Ratio (SNR):** 100dB (typical)  
- **Gain:** 30dB (typical)  
- **Package Type:** HSIP25 (Heat Sink Insulated Package)  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions:**  
- The STA474A is a high-performance digital power amplifier IC designed for stereo audio applications.  
- It features built-in protection circuits, including thermal shutdown and overcurrent protection.
