Description and Introduction

4 x 40 W BTL quad car radio power amplifier The TDA8571J is a quad bridge car radio power amplifier manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Type:** Quad bridge power amplifier  
- **Supply Voltage (Vs):** 6V to 18V (operating range)  
- **Output Power:**  
  - 4 × 20W (max) at 4Ω, 14.4V, 10% THD  
  - 4 × 12W (typical) at 4Ω, 14.4V, 1% THD  
- **Load Impedance:** 4Ω (minimum)  
- **Total Harmonic Distortion (THD):** Typically 0.1% at 1W output  
- **Standby Current:** <100µA  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** 17-pin SIL (Single In-Line) Power Package  

### **Descriptions:**
- Designed for car radio applications.
