Description and Introduction

TDA8542AT; 2 x 1.5 W BTL audio amplifier The TDA8542AT/N1 is a dual audio power amplifier manufactured by Philips (PHI).  

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 18V  
- **Output Power:** 1.1W per channel (at 10% THD, 8Ω, 12V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SO8 (Small Outline 8-pin)  
- **Quiescent Current:** 6mA (typical)  
- **Gain:** 26dB (fixed)  
- **Load Impedance:** 4Ω to 16Ω  

### **Descriptions:**  
- A dual BTL (Bridge-Tied Load) audio power amplifier designed for portable and consumer applications.  
- Features low power consumption and minimal external components.  
- Suitable for battery-powered devices like radios, portable audio players, and TVs.  

### **Features:**  
- **Low Standby Current:** Reduces power consumption in idle mode.  
- **Short-Circuit Protection:** Prevents damage from output shorts.  
- **Thermal Protection:** Shuts down in case of overheating.  
- **No External Components Required:** Minimal external circuitry needed for operation.  
- **Pop-Free Operation:** Reduces turn-on/off noise.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official Philips (PHI) documentation.

Application Scenarios & Design Considerations

TDA8542AT; 2 x 1.5 W BTL audio amplifier

Alternative Part Number
