Description and Introduction

5 W audio power amplifier The **TDA2611A** is an integrated circuit (IC) manufactured by **PHILIPS** (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Type:** Audio Power Amplifier IC  
- **Output Power:** 5 W (typical at 10% THD, 16 Ω load, 15 V supply)  
- **Supply Voltage Range:** 6 V to 35 V  
- **Quiescent Current:** 30 mA (typical)  
- **Total Harmonic Distortion (THD):** 0.5% (typical at 1 W, 1 kHz)  
- **Gain:** 30 dB (fixed)  
- **Load Impedance:** 4 Ω to 16 Ω  
- **Package:** SIL-9 (Single In-Line 9-pin package)  

### **Descriptions:**
- The TDA2611A is a monolithic Class-B audio amplifier designed for consumer applications such as TV sound, portable radios, and other audio systems.  
- It features **mute/standby functionality** and **thermal protection** to prevent damage from overheating.  
- The IC has a **fixed internal gain**, reducing the need for external components.  

### **Features:**
- **Low external component count**  
- **Short-circuit protection**  
- **Thermal overload protection**  
- **Mute/standby function**  
- **No switch-on/off clicks**  
- **Good ripple rejection**  

This information is based on the original PHILIPS datasheet for the TDA2611A.

Application Scenarios & Design Considerations

5 W audio power amplifier

Alternative Part Number

  • LM386N-1 --: Widely available low-voltage audio power amplifier in DIP-8, commonly used as a substitute for small audio amplifier ICs like the TDA2611A in low-power audio applications.
  • TDA2003 --: Class AB audio power amplifier in a 5-pin package with similar output power range, frequently used as an alternative in audio amplifier designs.
  • TDA2030A --: Popular audio power amplifier IC with higher output capability and similar application profile, suitable as a functional replacement where higher power is acceptable.
  • LM383 --: Audio power amplifier in the same low-wattage class with similar supply voltage range and output power, widely available and commonly used as a substitute in audio circuits.
  • LM386 --: Low-voltage audio power amplifier with similar function and pin-compatible style usage in small audio applications, though lower output power so verify requirements.
