Description and Introduction

15W Filter-Free Stereo Class-D Amplifier 32-VQFN -40 to 85 The TPA3117D2RHBT is a Class-D audio amplifier from Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:**  
  - 15W per channel into 4Ω at 10% THD+N (PVCC = 15V)  
  - 30W into 2Ω at 10% THD+N (PVCC = 15V)  
  - 10W per channel into 8Ω at 10% THD+N (PVCC = 15V)  
- **Supply Voltage (PVCC):** 4.5V to 26V  
- **Efficiency:** Up to 90%  
- **THD+N:** 0.1% (typical at 1W, 8Ω)  
- **Signal-to-Noise Ratio (SNR):** 102dB (A-weighted)  
- **Switching Frequency:** 300kHz to 500kHz (adjustable)  
- **Operating Temperature:** -40°C to 85°C  
- **Package:** 32-pin VQFN (RHB)  

### **Descriptions:**  
- The TPA3117D2RHBT is a stereo Class-D amplifier with an integrated feedback loop for improved audio performance.  
- It features a differential input to reduce noise and a built-in protection system (thermal, overcurrent, and undervoltage).  
- Designed for efficiency, it operates without an external heatsink in most applications.  

### **Features:**  
- **Advanced EMI Reduction:** Spread-spectrum modulation and edge-rate control.  
- **Flexible Gain Options:** 20dB, 26dB, or 32dB selectable via GAIN0/GAIN1 pins.  
- **Low Power Consumption:** <1µA shutdown current.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Single-Supply Operation:** Eliminates need for a negative voltage rail.
