Description and Introduction

750mW Audio Power Amplifier with DC Volume Control and Headphone Switch 8-VSSOP -40 to 85 The LM4865MM/NOPB is a power amplifier manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Type:** Audio Power Amplifier  
- **Output Power:** 1.1W per channel into 8Ω (at 5V, THD+N = 10%)  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin VSSOP (MSOP)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (typical at 1kHz, 1W, 8Ω)  
- **Shutdown Current:** 0.1μA (typical)  
- **Quiescent Current:** 4mA (typical)  
- **Gain:** Fixed at 6dB (2V/V)  

### **Descriptions:**  
The LM4865MM/NOPB is a dual bridge-connected audio power amplifier designed for portable applications. It operates from a single supply and delivers high-quality audio output with low distortion and noise. The device includes a thermal shutdown feature for protection against overheating.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration** – Eliminates output coupling capacitors  
- **Low Quiescent Current** – Extends battery life  
- **Thermal Shutdown Protection** – Prevents damage from overheating  
- **Space-Saving Package** – 8-pin VSSOP (MSOP)  
- **No External Components Required** – Minimal external circuitry needed  
- **Pop-and-Click Suppression** – Reduces noise during power-up/down
