Description and Introduction

4X30W STEREO BASH POWER AMPLIFIER The STA530 is a digital audio amplifier from STMicroelectronics. Here are the key specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Power:**  
  - 2 x 50W (4Ω, THD = 10%)  
  - 2 x 30W (8Ω, THD = 10%)  
- **Supply Voltage Range:** ±10V to ±30V  
- **Efficiency:** Up to 90% (Class D operation)  
- **Signal-to-Noise Ratio (SNR):** >100dB  
- **Total Harmonic Distortion + Noise (THD+N):** <0.1% (1W, 8Ω)  
- **Operating Frequency:** 300kHz switching frequency  
- **Protection Features:**  
  - Overcurrent protection  
  - Thermal shutdown  
  - Undervoltage lockout  

### **Descriptions:**  
- The STA530 is a dual-channel Class D audio amplifier designed for high-efficiency applications such as home audio systems, multimedia speakers, and professional audio equipment.  
- It integrates a PWM modulator and MOSFET output stage, reducing external component count.  

### **Features:**  
- **Class D Operation:** High efficiency with low heat dissipation.
