Description and Introduction

2.6W Stereo Audio Power Amplifiers and DirectDrive® Headphone Amplifiers The MAX9750CETI+T is a high-efficiency, Class D audio amplifier manufactured by Maxim Integrated. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX9750CETI+T  
- **Type:** Class D Audio Amplifier  
- **Output Power:**  
  - 2.8W into 4Ω at 5V (THD+N = 1%)  
  - 1.4W into 8Ω at 5V (THD+N = 1%)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.03% (typical)  
- **Signal-to-Noise Ratio (SNR):** 95dB (A-weighted)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Pin TQFN (5mm x 5mm)  

### **Descriptions:**
- The MAX9750CETI+T is a mono Class D amplifier designed for portable audio applications.  
- It features a high-efficiency, low-distortion design with a built-in spread-spectrum modulation scheme to reduce EMI.  
- The device includes an integrated boost converter to enhance output power while maintaining efficiency.  

### **Features:**  
- **High Efficiency:** Up to 90% efficiency reduces power consumption and extends battery life.  
- **Low EMI:** Spread-spectrum modulation minimizes electromagnetic interference.  
- **Integrated Boost Converter:** Allows higher output power from a low-voltage supply.  
- **Low Quiescent Current:** 4mA (typical) for power-saving operation.  
- **Click-and-Pop Suppression:** Reduces audible noise during power-up/down.  
- **Thermal and Short-Circuit Protection:** Ensures safe operation under fault conditions.  
- **Small Footprint:** 28-pin TQFN package (5mm x 5mm) for space-constrained applications.
