Description and Introduction

20W BRIDGE AMPLIFIER FOR CAR RADIO The TDA2005 is an integrated circuit (IC) manufactured by STMicroelectronics (ST). Below are the factual specifications, descriptions, and features of the TDA2005:

### **Specifications:**
- **Type:** Class AB Dual Audio Power Amplifier  
- **Output Power:**  
  - 20W (max) into 4Ω at 14.4V, 1kHz, 10% THD (bridged mode)  
  - 6W (per channel into 4Ω at 14.4V, 1kHz, 10% THD (stereo mode)  
- **Supply Voltage Range:** 8V to 18V  
- **Quiescent Current:** 100mA (typical)  
- **Total Harmonic Distortion (THD):** 0.1% (typical at 1W, 1kHz)  
- **Frequency Response:** 40Hz to 20kHz  
- **Gain:** 40dB (fixed)  
- **Operating Temperature Range:** -40°C to +150°C  

### **Descriptions:**
- The TDA2005 is a monolithic dual audio power amplifier designed for car radio applications.  
- It can operate in both **stereo (dual-channel)** and **bridged (mono)** configurations.  
- The IC includes built-in **short-circuit protection**, **thermal shutdown**, and **overload protection**.  
- It is housed in an **11-pin Multiwatt package** for efficient heat dissipation.  

### **Features:**
- High output power capability  
- Low distortion and noise  
- No external components required for operation (minimal external circuitry)  
- Mute/st-by function (optional)  
- Short-circuit and thermal protection  
- Suitable for automotive applications  

The TDA2005 is commonly used in **car audio systems**, portable speakers, and other audio amplification applications.  

(Note: All details are based on the official STMicroelectronics datasheet.)

Application Scenarios & Design Considerations

20W BRIDGE AMPLIFIER FOR CAR RADIO

Alternative Part Number

  • LM1875T --: Class AB audio power amplifier in TO-220 with comparable output power and supply range, widely used as a drop-in substitute for TDA2005 in bridge/ stereo audio designs.
  • TDA2030A --: Similar 14W audio power amplifier from the same manufacturer family, pin-compatible in many TDA2005 applications with minor external component adjustments.
  • TDA7265 --: Dual audio power amplifier offering similar output power and supply voltage range, suitable replacement where a stereo amplifier in the same class is required.
