Description and Introduction

2 x 150 W class-D power amplifier The TDA8950J is a high-efficiency Class-D audio amplifier manufactured by NXP Semiconductors. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Output Power:**  
  - 2 × 150 W (4 Ω, THD = 10%)  
  - 2 × 210 W (2 Ω, THD = 10%)  
  - 1 × 420 W (4 Ω, BTL mode, THD = 10%)  
- **Supply Voltage Range:** ±12.5 V to ±40 V  
- **Efficiency:** Up to 90%  
- **THD (Total Harmonic Distortion):** <0.1% (typical)  
- **Signal-to-Noise Ratio (SNR):** >100 dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** HSOP24 (Heat Sink Small Outline Package)  

### **Descriptions:**  
- The TDA8950J is a stereo or mono Class-D amplifier designed for high-power audio applications.  
- It uses a switching amplifier topology for high efficiency, reducing heat dissipation.  
- Suitable for professional audio systems, home theaters, and active speaker designs.  
- Includes protection features such as over-temperature, over-voltage, and short-circuit protection.  

### **Features:**  
- **High Efficiency:** Minimizes power loss and heat generation.  
- **Flexible Configuration:** Can operate in stereo (2-channel) or mono (BTL bridge-tied load) mode.  
- **Mute and Standby Functions:** Allows power-saving modes.  
- **Integrated Protection Circuits:** Includes thermal shutdown, over-voltage, and short-circuit protection.  
- **Low External Component Count:** Simplifies PCB design.  

This information is based on NXP's official datasheet for the TDA8950J. For detailed application notes, refer to the manufacturer's documentation.
