Description and Introduction

22WBTL or 2 x 11Wstereo power amplifier The TDA1519CTH is an integrated circuit (IC) manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Dual power amplifier (BTL configuration).  
- **Output Power:** 22W (typical at 10% THD, 4Ω load, 14.4V supply).  
- **Supply Voltage Range:** 6V to 18V (DC).  
- **Quiescent Current:** 65mA (typical).  
- **Total Harmonic Distortion (THD):** 0.1% (typical at 1W, 4Ω).  
- **Signal-to-Noise Ratio (SNR):** 80dB (typical).  
- **Operating Temperature Range:** -40°C to +85°C.  
- **Package:** SIL9P (9-pin single in-line package).  

### **Descriptions:**  
- Designed for car radio applications.  
- Operates in Bridge-Tied Load (BTL) mode for higher output power.  
- Includes thermal protection and short-circuit protection.  

### **Features:**  
- High output power capability.  
- Low standby current.  
- Requires minimal external components.  
- Built-in mute function.  
- Overvoltage and reverse polarity protection.  

This IC is optimized for automotive audio systems, providing efficient power amplification with protection features.

Application Scenarios & Design Considerations

22WBTL or 2 x 11Wstereo power amplifier

Alternative Part Number

  • LM1875T --: Class AB audio power amplifier in TO-220 package with comparable output power and supply range, widely used as a drop-in substitute for TDA1519 series in audio applications.
  • TDA2030A --: Popular 18W audio power amplifier with similar pinout and supply voltage range, commonly used as a replacement for TDA1519 devices in consumer audio designs.
  • TDA7265 --: Stereo audio power amplifier with comparable output power and supply requirements, suitable alternative when the original TDA1519CTH is unavailable.
  • TDA1519C --: Same TDA1519C audio amplifier family from the original Philips semiconductor business (now NXP), electrically equivalent in the standard package; drop-in for most designs.
  • TDA1552Q --: Similar 2x12W class-B car audio amplifier from the same TDA15xx series, widely used as a substitute where the TH package is not required.
