Description and Introduction

5 W mono BTL audio amplifier with DC volume control The TDA7056B is a mono BTL (Bridge Tied Load) audio power amplifier manufactured by PH (Philips Semiconductors).  

### **Specifications:**  
- **Supply Voltage (VP):** 4.5V to 18V  
- **Output Power (Po):**  
  - 6W (typical) at 10% THD, 16Ω load, 12V supply  
  - 3W (typical) at 10% THD, 8Ω load, 9V supply  
- **Gain (Gv):** Fixed at 40dB  
- **THD (Total Harmonic Distortion):** Typically 0.2% at Po = 1W, RL = 8Ω, f = 1kHz  
- **Quiescent Current (Iq):** Typically 7mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DIP8 (Dual In-line Package, 8 pins) or SO8 (Small Outline, 8 pins)  

### **Descriptions:**  
- The TDA7056B is designed for battery-powered portable audio applications.  
- It features a built-in DC volume control with logarithmic characteristics.  
- No external components are required for volume control.  
- The amplifier operates in BTL configuration, eliminating the need for an output coupling capacitor.  

### **Features:**  
- **Mono BTL Output:** No external coupling capacitor needed.  
- **Internal Fixed Gain:** 40dB (no external components required).  
- **DC Volume Control:** Adjustable via a DC voltage (0.5V to 3V).  
- **Low Standby Current:** Suitable for battery-powered devices.  
- **Short-Circuit Protection:** Thermal and output short-circuit protection.  
- **No Switch-On/Off Plops:** Smooth power-up and power-down.  

The TDA7056B is commonly used in portable radios, TVs, and other audio applications requiring low-power amplification.
