Description and Introduction

2.5W Audio Power Amplifier The LM380N-8 is a power amplifier IC manufactured by Texas Instruments. Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Audio Power Amplifier
- **Package:** 8-Pin DIP (Dual In-line Package)
- **Output Power:** 2.5W (typical) into 8Ω at 16V supply
- **Supply Voltage Range:** 10V to 22V
- **Quiescent Current:** 7mA (typical)
- **Gain:** Fixed at 50 (34 dB)
