Description and Introduction

2.9-W 3-Input Audio Subsystem with SmartGain&#153 Mono Class-D and DirectPath&#1 Headphone Amplifier 25-DSBGA -40 to 85 The TPA2051D3YFFR is a mono Class-D audio amplifier manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Power:** 1.1W into 8Ω at 5V (THD+N = 1%)  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Efficiency:** Up to 90% (Class-D operation)  
- **THD+N:** 0.2% (1kHz, 1W into 8Ω)  
- **SNR:** 95dB (A-weighted)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DSBGA (9-bump, 1.4mm x 1.4mm)  

### **Description:**  
The TPA2051D3YFFR is a high-efficiency, mono Class-D audio amplifier designed for portable applications. It features a low-power shutdown mode and operates from a single supply, making it suitable for battery-powered devices.  

### **Features:**  
- **Class-D Operation:** Reduces power dissipation and extends battery life.  
- **Integrated Depop Circuitry:** Minimizes audible pops and clicks during power-up/down.  
- **Low Quiescent Current:** 2.5mA (typical) for power efficiency.  
- **Thermal and Short-Circuit Protection:** Enhances reliability.  
- **Small Form Factor:** DSBGA package saves PCB space.  
- **Fixed Gain (6dB):** Simplifies design by eliminating external gain-setting components.
