Description and Introduction

SINGLE CHIP STEREO CASSETTE PLAYBACK SYSTEM The TDA7273 is a monolithic integrated circuit designed for use in audio applications, particularly as a stereo headphone driver. Below are the factual specifications, descriptions, and features from the available knowledge base:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Supply Voltage Range:** 1.8V to 6V  
- **Output Power:** 30mW per channel (at 5V, 32Ω load)  
- **Total Harmonic Distortion (THD):** 0.1% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** 4mA (typical)  
- **Signal-to-Noise Ratio (SNR):** 90dB (typical)  
- **Package:** SO-8 (MiniSO-8)  

### **Descriptions:**  
- The TDA7273 is a low-voltage stereo headphone amplifier designed for portable audio devices.  
- It features low power consumption, making it suitable for battery-operated applications.  
- The device includes built-in mute and standby functions for power-saving modes.  

### **Features:**  
- **Low Voltage Operation:** Works efficiently at voltages as low as 1.8V.  
- **Low Quiescent Current:** Ensures minimal power drain in standby mode.  
- **No External Components Required:** Simplifies circuit design (only requires decoupling capacitors).  
- **Short-Circuit Protection:** Built-in protection against output short circuits.  
- **Thermal Shutdown:** Prevents damage from overheating.  
- **Mute Function:** Allows muting the audio output when needed.
