Description and Introduction

Stereo Headphone Audio Amplifier, Pin Compatible with LM4880 and LM4881 The TPA6111A2D is a stereo audio power amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from TI's knowledge base:

### **Specifications:**  
- **Output Power:**  
  - 150 mW per channel into 16 Ω at 5 V  
  - 50 mW per channel into 32 Ω at 3.3 V  
- **Supply Voltage Range:** 2.5 V to 5.5 V  
- **Total Harmonic Distortion + Noise (THD+N):** 0.01% (typical)  
- **Signal-to-Noise Ratio (SNR):** 100 dB (typical)  
- **Gain:** Fixed at 6 dB (default) or externally adjustable  
- **Shutdown Current:** 0.1 μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The TPA6111A2D is a low-power stereo audio amplifier designed for portable applications such as smartphones, tablets, and portable media players. It features a low-noise design and operates efficiently at low supply voltages, making it suitable for battery-powered devices.  

### **Features:**  
- **Low Quiescent Current:** 2.6 mA (typical)  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces power supply noise interference  
- **Short-Circuit and Thermal Protection:** Enhances reliability  
- **Click-and-Pop Suppression:** Minimizes audible noise during power-up/down  
- **External Gain Configuration:** Allows flexibility in setting gain levels  
- **Differential Inputs:** Reduces common-mode noise
