Description and Introduction

300MW AT 3.3V SUPPLY AUDIO POWER AMPLIFIER WITH STANDBY MODE ACTIVE HIGH The TS4900 is a high-performance audio amplifier IC manufactured by STMicroelectronics. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range:** 4.5V to 26V  
- **Output Power:**  
  - 2.65W (into 4Ω at 5V, THD = 10%)  
  - 1.4W (into 8Ω at 5V, THD = 10%)  
  - Higher power achievable with increased supply voltage  
- **Efficiency:** Up to 90% (Class D operation)  
- **THD+N (Total Harmonic Distortion + Noise):** < 0.3% (typical)  
- **Signal-to-Noise Ratio (SNR):** > 90dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** PowerSSO-36  

### **Description:**  
The TS4900 is a Class D audio amplifier designed for portable and battery-powered applications. It provides high efficiency with low power consumption, making it suitable for devices like smartphones, tablets, and portable speakers. The amplifier features a differential input and requires minimal external components for operation.

### **Features:**  
- **Class D Operation:** High efficiency with low heat dissipation  
- **Low Quiescent Current:** Typically 2.5mA (shutdown mode < 1µA)  
- **Pop & Click Suppression:** Minimizes noise during power-up/down  
- **Short-Circuit & Thermal Protection:** Built-in safeguards  
- **Wide Supply Voltage Range:** Supports various battery configurations  
- **Small Footprint:** PowerSSO-36 package for space-constrained designs  

This information is based on STMicroelectronics' official documentation for the TS4900.
