Description and Introduction

DUAL LOW-VOLTAGE POWER AMPLIFIER The TDA2822D is a monolithic integrated circuit manufactured by STMicroelectronics (ST). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics (ST)  
- **Type:** Dual Low-Voltage Power Amplifier  
- **Package:** SO-8 (Small Outline 8-pin)  
- **Operating Voltage:** 1.8V to 15V  
- **Output Power:**  
  - 1W per channel (at 4Ω, 9V, THD = 10%)  
  - 650mW per channel (at 8Ω, 9V, THD = 10%)  
- **Quiescent Current:** 6mA (typical)  
- **Total Harmonic Distortion (THD):** 0.2% (typical at 1kHz, 1W)  
- **Frequency Response:** 40Hz to 20kHz  
- **Gain:** 39dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The TDA2822D is a dual-channel audio amplifier designed for portable and low-power applications.  
- It is commonly used in small audio devices such as radios, headphones, and multimedia speakers.  
- The IC is optimized for battery-powered applications due to its low-voltage operation.  

### **Features:**  
- **Dual-Channel Operation:** Supports stereo or bridge amplifier configurations.  
- **Low Quiescent Current:** Suitable for battery-powered devices.  
- **Wide Supply Voltage Range:** Operates from 1.8V to 15V.  
- **Minimal External Components:** Requires few external components for operation.  
- **Short-Circuit Protection:** Built-in protection against output short circuits.  
- **Thermal Shutdown:** Prevents damage from overheating.  

This information is based on the manufacturer's datasheet for the TDA2822D by STMicroelectronics.
