Description and Introduction

50-mW ULTRALOW VOLTAGE STEREO HEADPHONE AUDIO POWER AMPLIFIER The TPA6100A2DGKR is a stereo headphone amplifier manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Output Power:** 80mW per channel into 32Ω at 5V  
- **THD+N (Total Harmonic Distortion + Noise):** 0.01% (typical)  
- **SNR (Signal-to-Noise Ratio):** 105dB (typical)  
- **Shutdown Current:** 0.1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin VSSOP (MSOP)  

### **Descriptions:**  
- The TPA6100A2DGKR is a high-fidelity stereo headphone amplifier designed for portable audio applications.  
- It features an integrated depop circuit to minimize audible noise during power-up and shutdown.  
- The device operates efficiently with a low supply voltage, making it suitable for battery-powered systems.  

### **Features:**  
- **Low Quiescent Current:** 1.6mA (typical)  
- **Wide Supply Voltage Range (2.5V to 5.5V):** Supports various battery configurations.  
- **Short-Circuit and Thermal Protection:** Ensures device reliability.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces power supply noise interference.  
- **Small Footprint:** Ideal for space-constrained applications.
