Description and Introduction

Piezoelectric Speaker Driver The LM4960SQ is a high-performance audio power amplifier manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Power:** 2.1W (into 8Ω at 5V, THD+N = 1%)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical at 1kHz, 1W into 8Ω)  
- **SNR (Signal-to-Noise Ratio):** 100dB (typical)  
- **Shutdown Current:** <1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Pin LLP (Leadless Leadframe Package)  

### **Descriptions:**  
The LM4960SQ is a mono, filterless Class D audio amplifier designed for portable applications such as smartphones, tablets, and portable media players. It features high efficiency, low power consumption, and a small footprint, making it ideal for battery-powered devices.  

### **Features:**  
- **Filterless Class D Operation** – Eliminates the need for external LC filters.  
- **Low Quiescent Current** – 4mA (typical) for extended battery life.  
- **Pop-and-Click Suppression** – Minimizes audible noise during power-up/down.  
- **Thermal and Short-Circuit Protection** – Ensures device reliability.  
- **Shutdown Mode** – Reduces power consumption when not in use.  
- **Wide Supply Voltage Range** – Supports operation from 2.7V to 5.5V.
