Description and Introduction

Mono BTL audio amplifier with DC volume control The TDA7052B is a mono BTL (Bridge Tied Load) audio amplifier manufactured by PHILIPS (PHI).  

### **Specifications:**  
- **Output Power:** 1.2 W (typical at 6 V, 8 Ω, THD = 10%)  
- **Supply Voltage Range:** 4.5 V to 18 V  
- **Quiescent Current:** 4 mA (typical)  
- **Gain:** Fixed at 40 dB  
- **THD (Total Harmonic Distortion):** 0.2% (typical at 1 W, 8 Ω)  
- **Signal-to-Noise Ratio:** 80 dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DIP8 (Dual In-line Package) or SO8 (Small Outline Package)  

### **Descriptions:**  
- The TDA7052B is a low-voltage mono amplifier designed for portable audio applications.  
- It features built-in DC volume control and requires minimal external components.  
- The amplifier operates in BTL mode, eliminating the need for an output coupling capacitor.  

### **Features:**  
- No external components needed for DC volume control  
- Mute mode available  
- Short-circuit and thermal protection  
- Low power consumption  
- Suitable for battery-powered devices  

This information is based on the official datasheet from PHILIPS (PHI).

Application Scenarios & Design Considerations

Mono BTL audio amplifier with DC volume control

Alternative Part Number

  • LM386N-1 --: Classic low-voltage audio power amplifier in DIP-8, widely available and pin-compatible in function for small speaker applications.
  • TDA2822M --: Dual low-voltage audio amplifier in DIP-8, similar supply range and output power class, commonly used as a substitute in portable audio designs.
  • PAM8403 --: Modern class-D stereo audio amplifier offering higher efficiency and comparable output power, suitable replacement where board layout can be adapted.
