Description and Introduction

2 x 22 W BTL stereo car radio power amplifier with loudspeaker protection The TDA1553Q is an integrated circuit (IC) manufactured by PHILIPS (PHI). Below are the factual details about this component:

### **Manufacturer:**  
- **PHI (Philips Semiconductors, now NXP Semiconductors)**  

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 22W (per channel at 10% THD, 4Ω load)  
- **Operating Voltage Range:** 6V to 18V  
- **Number of Channels:** 2 (Stereo)  
- **Package Type:** Multiwatt15 (15-pin package)  
- **THD (Total Harmonic Distortion):** Typically 0.5% at 1W output  
- **Signal-to-Noise Ratio (SNR):** Typically 70dB  

### **Descriptions:**  
- The TDA1553Q is a class-AB stereo power amplifier IC designed for car radio and audio applications.
