Description and Introduction

4x7W OR 2x22W CAR RADIO POWER AMPLIFIER PLUS TRIPLE POWER SUPPLY The TDA7451 is an audio amplifier IC manufactured by STMicroelectronics (ST). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (ST)  
- **Type:** Audio Amplifier IC  
- **Output Power:** 2 x 10W (stereo) into 4Ω at 12V (THD = 10%)  
- **Supply Voltage Range:** 6V to 18V  
- **Operating Voltage:** Typically 12V  
- **Total Harmonic Distortion (THD):** 0.5% (typical at 1W, 4Ω)  
- **Signal-to-Noise Ratio (SNR):** > 80dB  
- **Standby Current:** < 100µA  
- **Package:** Multiwatt15 (15-pin)  

### **Descriptions:**
- The TDA7451 is a dual-bridge audio amplifier designed for car radio applications.  
- It features a built-in DC volume control, eliminating the need for external potentiometers.  
- The IC includes mute and standby functions for power-saving modes.  
- It is designed for high efficiency with low distortion and noise.  

### **Features:**
- **Dual-Bridge Configuration:** Supports stereo output without external coupling capacitors.  
- **DC Volume Control:** Adjustable via an external DC voltage (0V to 5V).  
- **Mute & Standby Functions:** Allows power-saving modes.  
- **Short-Circuit & Thermal Protection:** Built-in safeguards for reliability.  
- **Low External Component Count:** Simplifies PCB design.  
- **Wide Supply Voltage Range:** Suitable for automotive applications.  

This information is based on the manufacturer's datasheet and technical documentation.
