Description and Introduction

20-W MONO DIGITAL INPUT AUDIO AMPLIFIER The TPA3200D1DCP is a digital input Class-D audio amplifier manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Power:**  
  - 20W into 4Ω at 10% THD+N (PVDD = 16.5V)  
  - 10W into 8Ω at 10% THD+N (PVDD = 16.5V)  
- **Supply Voltage (PVDD):** 4.5V to 26V  
- **Efficiency:** Up to 90%  
- **Signal-to-Noise Ratio (SNR):** 100dB (A-weighted)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.1% (1W into 4Ω)  
- **Switching Frequency:** 384kHz or 768kHz (selectable)  
- **Input Interface:** I²S, TDM, or PDM digital audio input  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin HTSSOP (DCP)  

### **Descriptions:**  
- The TPA3200D1DCP is a single-channel, digital-input Class-D amplifier designed for high-efficiency audio applications.  
- It supports multiple digital audio input formats, including I²S, TDM, and PDM, making it suitable for various digital audio sources.  
- The device integrates a high-performance DAC and Class-D output stage, reducing external component requirements.  

### **Features:**  
- **Digital Input:** Supports I²S, TDM (up to 8 channels), and PDM (for microphones).  
- **Advanced Modulation:** Uses TI’s SmartGain™ technology for improved dynamic range and reduced distortion.  
- **Flexible Power Supply:** Operates from a wide 4.5V to 26V range, suitable for battery-powered and fixed-voltage systems.  
- **Integrated Protection:** Includes overcurrent, overtemperature, and undervoltage protection.  
- **Low Standby Power:** Consumes minimal power in shutdown mode.  
- **Small Footprint:** HTSSOP package enables compact PCB designs.  

This information is based solely on TI's official documentation for the TPA3200D1DCP.
