Description and Introduction

2 x 22 W or 4 x 11 W single-ended car radio power amplifier The TDA1558Q is a monolithic integrated audio amplifier manufactured by PHIL (Philips Semiconductors).  

### **Specifications:**  
- **Type:** Stereo BTL (Bridge-Tied Load) or quad amplifier  
- **Output Power:**  
  - 2 x 22W (stereo BTL, THD = 10%)  
  - 4 x 11W (quad, THD = 10%)  
- **Supply Voltage Range:** 6V to 18V (DC)  
- **Operating Voltage:** Typically 14.4V (car radio applications)  
- **Total Harmonic Distortion (THD):** <0.5% (typical)  
- **Signal-to-Noise Ratio (SNR):** >80dB  
- **Standby Current:** <100µA  
- **Load Impedance:** 4Ω (minimum)  

### **Descriptions:**  
- The TDA1558Q is designed for car radio and other audio applications requiring high output power with minimal external components.  
- It features built-in protection circuits against short circuits, thermal overload, and reverse polarity.  
- The amplifier can operate in stereo BTL mode (2-channel) or quad mode (4-channel).  

### **Features:**  
- **High Output Power:** Capable of delivering up to 22W per channel in BTL mode.  
- **Low Standby Current:** Reduces power consumption when not in use.  
- **Protection Circuits:** Includes thermal shutdown, short-circuit protection, and reverse polarity protection.  
- **Mute/Standby Function:** Allows power-saving mode and smooth turn-on/off.  
- **Minimal External Components:** Requires few external components for operation.  
- **Flexible Configuration:** Can be used in stereo or quad output modes.  

The TDA1558Q is housed in a 17-pin SIL (Single In-Line) plastic power package.
