Description and Introduction

2 x 1.5 W BTL audio amplifier The TDA8542AT is a monolithic integrated circuit manufactured by PHILIPS. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Type:** Audio Amplifier IC  
- **Package:** SO16 (Small Outline 16-pin package)  
- **Operating Voltage Range:** 4.5V to 18V  
- **Output Power:** 1.1W per channel (at 12V, 8Ω, THD = 10%)  
- **Number of Channels:** 2 (Stereo)  
- **Total Harmonic Distortion (THD):** Typically 0.2% (at 1W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** Typically 80dB  
- **Gain:** Fixed at 26dB  
- **Quiescent Current:** Typically 9mA  

### **Descriptions:**
- The TDA8542AT is a dual bridge-tied load (BTL) audio power amplifier designed for portable audio applications.  
- It is optimized for low-voltage operation, making it suitable for battery-powered devices.  
- The IC features short-circuit protection and thermal shutdown for reliability.  

### **Features:**
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **No External Components Required:** Minimal external circuitry needed.  
- **BTL Configuration:** Eliminates the need for output coupling capacitors.  
- **Standby Mode:** Low quiescent current in standby for power saving.  
- **Mute Function:** Allows muting of the audio output.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the IC from output shorts.  

This information is based solely on the manufacturer's datasheet for the TDA8542AT.
