Description and Introduction

6W 2-Channel, Bridge 19W typ Power Amplifier The LA4440 is an integrated circuit (IC) manufactured by **SANYO** (now part of ON Semiconductor). Below are the specifications, descriptions, and features of the LA4440:  

### **Specifications:**  
- **Type:** Dual-channel audio power amplifier IC  
- **Output Power:**  
  - 6W per channel (at 12V, 4Ω, 10% THD)  
  - 19W in bridge-tied load (BTL) mode (at 12V, 4Ω, 10% THD)  
- **Supply Voltage Range:** 9V to 18V (recommended)  
- **Quiescent Current:** 45mA (typical)  
- **Total Harmonic Distortion (THD):** 0.3% (typical at 1W, 4Ω)  
- **Frequency Response:** 20Hz to 20kHz  
- **Operating Temperature Range:** -20°C to +75°C  
- **Package Type:** SIP-12 (Single Inline Package with 12 pins)  

### **Descriptions:**
