Description and Introduction

FILTER IC FOR SUMM-DELTA MODULATION SYSTEM DA CONVERTER The TA2028F is a Class-D audio power amplifier IC manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Type:** Class-D Audio Power Amplifier  
- **Output Power:**  
  - 10W per channel (into 4Ω at 10% THD, VCC = 12V)  
  - 6W per channel (into 8Ω at 10% THD, VCC = 12V)  
- **Supply Voltage (VCC):** 4.5V to 14.4V  
- **Total Harmonic Distortion (THD):** Typically 0.1% (1W, 1kHz, 8Ω)  
- **Efficiency:** Up to 90% (typical for Class-D amplifiers)  
- **Operating Temperature Range:** -20°C to +75°C  
- **Package:** HSOP-28 (Heat Sink Small Outline Package)  

### **Descriptions:**  
- The TA2028F is a monolithic Class-D amplifier IC designed for high-efficiency audio applications.  
- It integrates a PWM modulator, gate drivers, and MOSFET output stage.  
- Suitable for portable audio devices, car audio systems, and home audio applications.  

### **Features:**  
- **Low Power Consumption:** High efficiency reduces heat dissipation.  
- **Built-in Protections:** Includes overcurrent, overvoltage, and thermal shutdown protection.  
- **Standby Function:** Low power consumption in standby mode.  
- **Single-Supply Operation:** Simplifies power supply design.  
- **Differential Inputs:** Reduces noise and improves audio quality.  
- **Compact Package:** HSOP-28 with a heat sink for thermal management.  

This information is based on Toshiba's official datasheet for the TA2028F.
