Description and Introduction

Low Noise Preamplifier For Autoreverse Car Stereo The TA2025P is a Class-T digital audio amplifier IC manufactured by Tripath Technology (not Toshiba, as initially mentioned). Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **Tripath Technology** (now defunct, acquired by Cirrus Logic in 2007).  

### **Specifications:**  
- **Type:** Class-T Digital Audio Amplifier (patented switching technology).  
- **Output Power:**  
  - **Stereo Mode (4Ω):** 12W per channel (THD+N = 10%).  
  - **Stereo Mode (8Ω):** 6W per channel (THD+N = 10%).  
  - **Bridged Mono Mode (8Ω):** 25W (THD+N = 10%).  
- **Supply Voltage Range:** 4.5V to 14V.  
- **Efficiency:** Up to 88% (reduces heat dissipation).  
- **THD+N (Total Harmonic Distortion + Noise):** Typically <0.1% (at 1W, 8Ω).  
- **Signal-to-Noise Ratio (SNR):** >95dB (A-weighted).  
- **Frequency Response:** 20Hz–20kHz (±0.5dB).  
- **Package:** 20-pin PowerDIP or SOIC.  

### **Descriptions & Features:**  
- **Class-T Technology:** Combines Class-D efficiency with high-fidelity audio performance.  
- **Low Heat Generation:** Efficient power usage reduces need for large heatsinks.  
- **Minimal External Components:** Requires few external parts for operation.  
- **Protection Features:** Includes thermal shutdown, overcurrent, and undervoltage protection.  
- **Applications:** Used in compact audio systems, multimedia speakers, and portable amplifiers.  

### **Note:**  
- The TA2025P is obsolete but was popular in DIY audio projects due to its simplicity and performance.
