Description and Introduction

High-Performance 68W Audio Power Amplifier with Mute The LM3886 is a high-performance audio power amplifier manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Power:**  
  - 68W continuous average into 4Ω at VCC = ±28V  
  - 38W into 8Ω at VCC = ±28V  
  - 50W into 8Ω at VCC = ±35V  
- **Supply Voltage Range:** ±10V to ±42V  
- **Peak Output Current:** 11.5A  
- **Total Harmonic Distortion + Noise (THD+N):** 0.03% (typical) at 1W, 1kHz, 8Ω  
- **Signal-to-Noise Ratio (SNR):** ≥92dB (A-weighted)  
- **Slew Rate:** 19V/µs  
- **Input Impedance:** 150kΩ (typical)  
- **Gain Bandwidth Product:** 8MHz  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package:** TO-220 (11-pin)  

### **Descriptions:**  
The LM3886 is a high-fidelity audio power amplifier capable of delivering high output power with low distortion. It features advanced protection circuitry, including thermal shutdown, instantaneous peak current limiting, and an under-voltage lockout to prevent damage.  

### **Features:**  
- **Mute Function:** Allows muting the amplifier to reduce turn-on/off transients.  
- **SPiKe™ Protection:** Safeguards against overvoltage, undervoltage, overloads, and thermal issues.  
- **High-Performance Audio:** Low noise and distortion for high-quality sound reproduction.  
- **Wide Supply Range:** Operates efficiently across a broad voltage range.  
- **Robust Thermal Performance:** Designed for reliable operation under high-power conditions.  

The LM3886 is commonly used in stereo amplifiers, home theater systems, and professional audio applications.

Description and Introduction

High-Performance 68W Audio Power Amplifier with Mute The LM3886 is a high-performance audio power amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Power:**  
  - 68W continuous average into a 4Ω load at VS = ±35V  
  - 38W into an 8Ω load at VS = ±28V  
- **Supply Voltage Range (VS):** ±10V to ±42V  
- **Peak Output Current:** 11.5A  
- **Total Harmonic Distortion + Noise (THD+N):**  
  - 0.03% at 1W, 1kHz  
  - 0.1% at 60W, 4Ω, 1kHz  
- **Signal-to-Noise Ratio (SNR):** ≥92dB (A-weighted)  
- **Input Impedance:** ~150kΩ  
- **Slew Rate:** 19V/µs  
- **Bandwidth:** 8MHz  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package:** TO-220 or 11-lead Multiwatt (both non-isolated)  

### **Descriptions:**  
The LM3886 is a monolithic power amplifier designed to deliver high-performance audio with minimal external components. It features advanced protection circuitry, including thermal shutdown, instantaneous peak current limiting, and an under-voltage lockout to prevent damage during operation.  

### **Features:**  
- **Mute Function:** Allows muting the amplifier to reduce turn-on/off transients.  
- **SPiKe™ Protection:** Safeguards against overvoltage, undervoltage, overloads, and thermal issues.  
- **High Output Current:** Capable of driving low-impedance loads (down to 2Ω in some configurations).  
- **Wide Supply Voltage Range:** Supports flexible power supply configurations.  
- **Low Distortion:** Ensures high-fidelity audio reproduction.  
- **Thermal Protection:** Automatically shuts down if the die temperature exceeds safe limits.  

This information is based on TI's official datasheet for the LM3886.
