Description and Introduction

10-W Mono Class-D Audio Power Amplifier with SpeakerGuard™ (TPA3111) 28-HTSSOP -40 to 85 The TPA3111D1PWPR is a Class-D audio amplifier manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Output Power:** Up to 15W per channel (into 4Ω at 10% THD+N, PVCC = 15V)  
- **Supply Voltage (PVCC):** 4.5V to 26V  
- **Efficiency:** Up to 90% (reducing heat sink requirements)  
- **THD+N:** 0.1% (typical at 1W into 4Ω)  
- **Signal-to-Noise Ratio (SNR):** 102dB (A-weighted)  
- **Switching Frequency:** 1.2MHz (adjustable)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** HTSSOP-28 (PowerPAD™)  

### **Description:**  
The TPA3111D1PWPR is a mono, high-efficiency Class-D audio amplifier designed for driving speakers with minimal external components. It integrates a high-performance PWM modulator and MOSFET power stage, making it suitable for portable and space-constrained applications.  

### **Features:**  
- **Advanced EMI Suppression:** Reduces interference in sensitive applications.  
- **Integrated Feedback:** Improves PSRR and reduces output filter dependency.  
- **Short-Circuit Protection:** Includes thermal and overcurrent protection.  
- **Low Idle Power Consumption:** ~15mA (typical at no load).  
- **Flexible Gain Settings:** Adjustable via external resistors (20dB, 26dB, 32dB, 36dB).  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Mono Configuration:** Optimized for single-channel audio amplification.
