Description and Introduction

Stereo 25W Audio Power Amplifier with Mute and Standby Modes The LM4731TA is a stereo audio power amplifier manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:**  
  - 25W per channel into 8Ω at ±25V (stereo)  
  - 35W per channel into 4Ω at ±22V (stereo)  
- **Supply Voltage Range:** ±10V to ±25V  
- **Total Harmonic Distortion + Noise (THD+N):** 0.03% (typical at 1W, 1kHz)  
- **Signal-to-Noise Ratio (SNR):** 110dB (typical)  
- **Input Impedance:** 30kΩ (typical)  
- **Gain Bandwidth Product:** 8MHz (typical)  
- **Slew Rate:** 15V/µs (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 15-pin TO-220 (LM4731TA)  

### **Description:**  
The LM4731TA is a high-performance, dual-channel audio amplifier designed for stereo applications. It integrates two independent amplifiers in a single package, providing efficient power amplification for audio systems.  

### **Features:**  
- **Dual-Channel Operation:** Two independent amplifiers in one IC.  
- **Mute Function:** Allows muting of the output signal.  
- **Standby Mode:** Low-power standby mode for energy efficiency.  
- **Thermal Protection:** Built-in thermal shutdown to prevent overheating.  
- **Short-Circuit Protection:** Safeguards against output shorts.  
- **Wide Supply Voltage Range:** Supports flexible power supply configurations.  
- **High Output Power:** Suitable for mid-range audio applications.  

This information is based solely on the manufacturer's datasheet for the LM4731TA.
