Description and Introduction

Mono 2W Class D Amplifier The MAX98300EWL+T is a digital input Class D audio amplifier manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Output Power:** Up to 3.2W into 4Ω (at 5V supply)  
- **Efficiency:** Up to 90%  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **THD+N:** 0.02% (1W into 4Ω, 5V supply)  
- **Signal-to-Noise Ratio (SNR):** 100dB (A-weighted)  
- **Digital Input Interface:** I²S, left-justified, right-justified, TDM  
- **Sample Rates Supported:** 8kHz to 96kHz  
- **Package:** 9-bump WLP (1.63mm x 1.63mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX98300EWL+T is a high-efficiency, digital-input Class D amplifier designed for portable audio applications. It eliminates the need for an external DAC by directly accepting digital audio signals, reducing system complexity and power consumption.  

### **Features:**  
- **Ultra-Low EMI:** Spread-spectrum modulation reduces EMI emissions.  
- **Flexible Digital Input:** Supports multiple audio formats (I²S, TDM, etc.).  
- **Integrated Feedback:** Ensures high audio fidelity.  
- **Low Quiescent Current:** 2.5mA (typical) for power efficiency.  
- **Automatic Gain Control (AGC):** Prevents clipping and distortion.  
- **Pop-and-Click Suppression:** Minimizes audible noise during power-up/down.  

This device is ideal for smartphones, tablets, portable speakers, and other battery-powered audio applications.
