Description and Introduction

40V 4.5A QUAD POWER HALF BRIDGE The STA508 is a dual BTL (Bridge-Tied Load) audio power amplifier manufactured by STMicroelectronics.  

### **Specifications:**  
- **Output Power:** Up to 2 × 45W (4Ω, 22V, THD = 10%)  
- **Operating Voltage Range:** 8V to 22V  
- **Efficiency:** Up to 90% (with proper heat sinking)  
- **THD+N (Total Harmonic Distortion + Noise):** <0.1% (typical)  
- **Signal-to-Noise Ratio (SNR):** >100dB  
- **Standby Current:** <1µA (low-power mode)  
- **Package:** PowerSO-36 (thermally enhanced)  

### **Descriptions:**  
- The STA508 is designed for high-efficiency Class-D amplification, making it suitable for automotive and home audio applications.  
- It features built-in protection circuits (short-circuit, over-temperature, and over-voltage protection).  
- The amplifier operates in a bridge configuration, eliminating the need for output coupling capacitors.  

### **Features:**  
- **Dual BTL Class-D Amplifier:** Supports two independent channels.  
- **High Efficiency:** Reduces power dissipation and heat generation.  
- **Mute and Standby Functions:** Allows power-saving modes.  
- **Pop & Click Suppression:** Minimizes noise during power-on/off.  
- **Thermal Protection:** Shuts down in case of overheating.  
- **Short-Circuit Protection:** Safeguards the amplifier and speakers.  

This information is based on STMicroelectronics' official datasheet for the STA508.

Description and Introduction

40V 4.5A QUAD POWER HALF BRIDGE The STA508 is a digital audio power amplifier from STMicroelectronics (STM). Here are the key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Power:** Up to 45W per channel (4Ω, 10% THD+N) or 28W per channel (8Ω, 10% THD+N).  
- **Supply Voltage Range:** ±12V to ±30V (dual supply).  
- **Efficiency:** Up to 90% (Class D operation).  
- **Signal-to-Noise Ratio (SNR):** >100dB (A-weighted).  
- **Total Harmonic Distortion + Noise (THD+N):** <0.05% (1W, 8Ω).  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** PowerSSO-36 (exposed pad for thermal dissipation).  

### **Descriptions:**
- The STA508 is a **Class D amplifier** designed for high-efficiency audio applications.  
- It integrates a **PWM modulator**, **gate drivers**, and **MOSFET output stage** for compact design.  
- Supports **stereo (2-channel) or mono (bridged) operation**.  
- Includes **protection features** like overcurrent, overtemperature, and undervoltage lockout.  

### **Features:**
- **High Efficiency:** Reduces power dissipation and heat generation.  
- **Low EMI:** Optimized for minimal electromagnetic interference.  
- **Standby Mode:** Low-power consumption when idle.  
- **Pop & Click Suppression:** Minimizes noise during power-on/off.  
- **Flexible Input:** Accepts analog audio signals (PWM input not required).
