Description and Introduction

5W AUDIO AMPLIFIER WITH MUTING The TDA1905 is an integrated circuit (IC) manufactured by SGS (now part of STMicroelectronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Type:** Audio Power Amplifier  
- **Output Power:** 4 W (typical at 4 Ω, 14.4 V, THD = 10%)  
- **Supply Voltage Range:** 8 V to 18 V  
- **Quiescent Current:** 45 mA (typical)  
- **Total Harmonic Distortion (THD):** 0.5% (typical at 1 W, 4 Ω)  
- **Operating Temperature Range:** -30°C to +85°C  
- **Package:** Multiwatt11 (11-pin vertical power package)  

### **Descriptions:**
- The TDA1905 is a monolithic Class AB audio amplifier designed for car radio applications.  
- It includes built-in thermal protection and short-circuit protection.  
- The IC is optimized for low distortion and high efficiency in automotive audio systems.  

### **Features:**
- **High Output Power:** Capable of delivering up to 4 W into a 4 Ω load.  
- **Low Standby Current:** Reduces power consumption when idle.  
- **Mute Function:** Allows muting the amplifier when needed.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards against output shorts.  
- **Wide Supply Voltage Range:** Suitable for automotive power systems.  

This information is based on the original datasheet from SGS (now STMicroelectronics).
