Description and Introduction

STEREO 15W (4?) CLASS-T? DIGITAL AUDIO AMPLIFIER USING DIGITAL POWER PROCESSING? TECHNOLOGY The TA2024B is a Class-T digital audio amplifier IC manufactured by STMicroelectronics (ST). Below are the specifications, descriptions, and features based on the manufacturer's data:

### **Specifications:**
- **Supply Voltage (VDD):** 4.5V to 14V  
- **Output Power:**  
  - 15W per channel (4Ω, 12V, 1% THD+N)  
  - 10W per channel (8Ω, 12V, 1% THD+N)  
- **Efficiency:** Up to 88%  
- **Signal-to-Noise Ratio (SNR):** >100dB (A-weighted)  
- **Total Harmonic Distortion + Noise (THD+N):** <0.1% (1W, 8Ω)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-pin PowerSSO  

### **Description:**  
The TA2024B is a high-efficiency Class-T digital audio amplifier that combines the benefits of Class-D amplifiers with advanced modulation techniques for improved audio performance. It is designed for applications requiring high-quality audio output with minimal power dissipation.

### **Features:**  
- **Patented Class-T Architecture:** Provides high efficiency while maintaining audio fidelity.  
- **Low EMI Emissions:** Complies with international standards.  
- **Integrated Protection Circuits:** Includes thermal shutdown, overcurrent, and undervoltage protection.  
- **Single-Supply Operation:** Simplifies power supply design.  
- **Mute Function:** Allows for controlled startup and shutdown.  
- **Wide Supply Voltage Range:** Supports operation from 4.5V to 14V.  
- **Minimal External Components:** Reduces system cost and PCB space.
