Description and Introduction

Low Voltage I2S 16-Bit Stereo DAC with Stereo Headphone Power Amplifiers and Volume Control2S 16-Bit Stereo DAC with Stereo Headphone ... The LM4921ITL is a manufacturer by National Semiconductor (NS). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Type:** Audio Amplifier  
- **Package:** 10-WSON (3x3mm)  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **Output Power:** Up to 1.1W (into 8Ω at 5V)  
- **THD+N (Total Harmonic Distortion + Noise):** <1%  
- **Shutdown Current:** <1µA  
- **Quiescent Current:** 4mA (typical)  
- **PSRR (Power Supply Rejection Ratio):** 70dB (at 217Hz)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LM4921ITL is a mono, bridge-tied load (BTL) audio power amplifier designed for portable applications. It delivers high-quality audio output with low distortion and noise. The device operates efficiently from a single supply voltage, making it suitable for battery-powered devices like smartphones, tablets, and portable media players.  

### **Features:**  
- **Bridge-Tied Load (BTL) Configuration:** Eliminates the need for output coupling capacitors.  
- **Low Power Consumption:** Optimized for battery life.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the amplifier and connected components.  
- **Pop-and-Click Suppression:** Minimizes audible noise during power-up/down.  
- **Space-Saving Package:** 10-WSON (3x3mm) for compact PCB designs.  

This information is strictly based on the manufacturer's datasheet and specifications.
