Description and Introduction

Low voltage mono/stereo power amplifier The TDA7050T is a mono BTL (Bridge Tied Load) output amplifier manufactured by NXP Semiconductors. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 4.5V to 18V  
- **Output Power:** 1.1W (typical at 12V, 8Ω, THD = 10%)  
- **Quiescent Current:** 4mA (typical)  
- **Total Harmonic Distortion (THD):** 0.2% (typical at 1W, 8Ω)  
- **Gain:** Fixed at 40dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SO8 (Small Outline 8-pin)  

### **Descriptions:**
- The TDA7050T is a low-voltage mono amplifier designed for battery-powered portable audio applications.  
- It features a bridge-tied load (BTL) configuration, eliminating the need for an output coupling capacitor.  
- The device includes thermal protection and short-circuit protection.  

### **Features:**
- **No External Components Required:** Minimal external components needed for operation.  
- **Low Standby Current:** Suitable for battery-powered devices.  
- **Mute Function:** Controlled via a dedicated pin (Pin 1).  
- **Short-Circuit Safe:** Built-in protection against short circuits.  
- **Thermal Protection:** Prevents damage from overheating.
