Description and Introduction

1 Watt Audio Power Amplifier The LM4890MMX is a mono bridged audio power amplifier manufactured by Texas Instruments.  

### **Specifications:**  
- **Output Power:** 1.1W into 8Ω at 5V (THD+N = 10%)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Quiescent Current:** 2.6mA (typical)  
- **Shutdown Current:** 0.01μA (typical)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.2% (typical at 1kHz, 1W into 8Ω)  
- **PSRR (Power Supply Rejection Ratio):** 70dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin VSSOP (MSOP)  

### **Descriptions:**  
The LM4890MMX is designed for portable audio applications, such as mobile phones and portable media players. It features a low-power consumption design with a shutdown mode to extend battery life. The amplifier operates in bridge-tied load (BTL) mode, eliminating the need for an output coupling capacitor.  

### **Features:**  
- **Bridged Output (BTL) Configuration** – No output capacitor required  
- **Low Quiescent Current** – 2.6mA (typical)  
- **Low Shutdown Current** – 0.01μA (typical)  
- **Improved PSRR** – Reduces power supply noise  
- **Thermal Shutdown Protection** – Prevents damage from overheating  
- **Short-Circuit Protection** – Protects the device during faults  
- **Space-Saving Package** – 8-pin VSSOP (MSOP)
