Description and Introduction

QUAD POWER AMPLIFIER FOR CAR RADIO The TDA7370 is a car radio amplifier manufactured by STMicroelectronics (ST). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** AB class amplifier  
- **Output Power:**  
  - 2 x 20W (4Ω, 14.4V, THD = 10%)  
  - 2 x 12W (4Ω, 12V, THD = 10%)  
  - 1 x 40W (bridged mode, 4Ω, 14.4V, THD = 10%)  
- **Supply Voltage Range:** 8V to 18V  
- **Operating Voltage:** 14.4V (typical)  
- **Standby Current:** < 1mA  
- **Total Harmonic Distortion (THD):** 0.1% (typical at 1W, 4Ω)  
- **Signal-to-Noise Ratio (SNR):** > 80dB  
- **Gain:** 26dB (fixed)  
- **Package:** Multiwatt15 (vertical or horizontal mounting)  

### **Descriptions:**  
- The TDA7370 is a dual-bridge amplifier designed for car radio applications.  
- It supports both stereo and mono (bridged) configurations.  
- Features built-in protection circuits against short circuits, thermal overload, and overvoltage.  
- Requires minimal external components for operation.  

### **Features:**  
- **Dual-Bridge or Stereo Operation:** Can be configured in 2-channel stereo or single-channel bridged mode.  
- **Mute and Standby Functions:** Allows power-saving modes.  
- **Short-Circuit Protection:** Protects output stages.  
- **Thermal Shutdown:** Prevents overheating.  
- **Low External Component Count:** Simplifies PCB design.  
- **High Output Power:** Suitable for car audio systems.  

This information is strictly based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

QUAD POWER AMPLIFIER FOR CAR RADIO

Alternative Part Number

  • LM1875T --: Single-channel 20W class-AB audio power amplifier in TO-220, widely used as a drop-in substitute for small ST car-radio amplifier ICs with similar supply range and pinout.
  • TDA2003 --: Classic 10W car-radio audio amplifier in Pentawatt package from the same manufacturer family, commonly used when TDA7370 is unavailable for lower-power applications.
  • TDA1552Q --: Dual 22W class-B car audio amplifier in a similar power package, offering comparable output power and supply voltage for automotive audio designs.
  • TDA7375 --: Same TDA737x family audio power amplifier with comparable output power and pinout, direct functional replacement from the successor company.
  • TDA7377 --: Higher-power quad audio amplifier in the same series, commonly used as an upgrade substitute with similar supply and application circuit.
  • TDA7384 --: Similar quad bridge audio power amplifier for car radio applications, electrically compatible with minor circuit adjustments.
