Description and Introduction

LM4810 Dual 105mW Headphone Amplifier with Active-High Shutdown Mode The LM4810LDX is a manufacturer part from NS/PBF (National Semiconductor, now part of Texas Instruments). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Type:** Audio Power Amplifier  
- **Output Power:** 105mW per channel into 32Ω at 3.3V  
- **Number of Channels:** 2 (Stereo)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical)  
- **Shutdown Current:** 0.01μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-WSON (3mm x 3mm)  

### **Descriptions:**
The LM4810LDX is a dual, bridge-tied load (BTL) audio power amplifier designed for portable applications. It operates from a single supply and delivers high-quality audio output with low distortion. The device includes an internal shutdown feature to minimize power consumption when not in use.
