Description and Introduction

LOW NOISE PREAMPLIFIER FOR AUTOREVERSE CAR STEREO The TA2025 is a Class-T digital audio amplifier IC manufactured by Tripath Technology. Here are its specifications, descriptions, and features:

### **Specifications:**
- **Output Power:**  
  - 15W per channel into 4Ω (stereo mode)  
  - 30W into 8Ω (bridged mono mode)  
- **Supply Voltage Range:** 8V to 14V  
- **Efficiency:** Up to 88% (reduces heat dissipation)  
- **Total Harmonic Distortion + Noise (THD+N):** <0.1%  
- **Signal-to-Noise Ratio (SNR):** >90dB  
- **Frequency Response:** 20Hz – 20kHz (±0.5dB)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin DIP (Dual Inline Package)  

### **Descriptions:**
- The TA2025 is a high-efficiency Class-T amplifier that combines digital switching technology with analog signal processing.  
- It is designed for low-power audio applications such as multimedia speakers, portable audio systems, and automotive audio.  
- The chip integrates a PWM modulator, gate drivers, and MOSFET output stage, reducing external component count.  

### **Features:**
- **Patented Class-T Technology:** Delivers high-quality audio with low distortion.  
- **Low Heat Generation:** Due to high efficiency, reducing the need for large heat sinks.  
- **Overcurrent & Thermal Protection:** Built-in safeguards to prevent damage.  
- **Single-Supply Operation:** Simplifies power supply design.  
- **Standby Mode:** Low power consumption when idle.  
- **Minimal External Components:** Reduces PCB space and cost.  

The TA2025 is now discontinued, as Tripath ceased operations in 2007. However, it remains popular in DIY audio projects and legacy designs.
