Description and Introduction

6W AUDIO AMPLIFER WITH STAND-BY The TDA7245A is a monolithic integrated circuit designed as a car radio audio amplifier. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Output Power:**  
  - 20W (into 4Ω at 14.4V, THD = 10%)  
  - 11W (into 4Ω at 12V, THD = 10%)  
- **Supply Voltage Range:** 8V to 18V  
- **Operating Temperature Range:** -40°C to +105°C  
- **Standby Current:** < 50mA  
- **Total Harmonic Distortion (THD):** < 0.5% (at 1W into 4Ω)  
- **Signal-to-Noise Ratio (SNR):** > 70dB  

### **Descriptions:**  
- The TDA7245A is a class AB audio amplifier IC primarily used in automotive applications, such as car radios.  
- It features built-in thermal and short-circuit protection for reliability.  
- The device is housed in a Multiwatt11 package for efficient heat dissipation.  

### **Features:**  
- **High Output Power:** Capable of delivering up to 20W under optimal conditions.  
- **Wide Supply Voltage Range:** Supports operation from 8V to 18V, making it suitable for automotive environments.  
- **Low Standby Current:** Ensures minimal power consumption when not in use.  
- **Protection Circuits:** Includes thermal shutdown and short-circuit protection.  
- **Mute Function:** Allows for muting the audio output when needed.  
- **Few External Components:** Simplifies circuit design and reduces board space.  

The TDA7245A is optimized for automotive audio applications, providing robust performance with built-in safeguards.

Application Scenarios & Design Considerations

6W AUDIO AMPLIFER WITH STAND-BY

Alternative Part Number

  • LM1875T --: Audio power amplifier in TO-220 package with comparable output power and supply range, widely used as a drop-in substitute for small Class-AB audio amps.
  • TDA2030A --: Classic 18W audio power amplifier in the same family of applications, similar pinout and supply voltage, easy replacement for low-power audio stages.
  • TDA7265 --: Stereo audio power amplifier with similar supply and output capability, suitable when a slightly higher-power alternative is acceptable.
  • TDA7245 --: Same TDA7245 series audio amplifier without the A suffix; nearly identical electrical characteristics and pinout, widely available as a direct substitute.
  • TDA2003 --: Classic 10W audio power amplifier in the same family of automotive audio ICs; similar supply range and output power, commonly used as a replacement in audio amplifier circuits.
  • LM383 --: Comparable 5-8W audio power amplifier with similar supply voltage range and package style, usable as a functional alternative when the original is unavailable.
