Description and Introduction

2.6W Stereo Audio Power Amplifiers and DirectDrive® Headphone Amplifiers The MAX9750CETI+C2U is a high-efficiency, mono Class D audio power amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:** Up to 2.8W into 4Ω at 5V supply (THD+N = 1%)  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Efficiency:** Up to 90% (Class D operation)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.03% (typical at 1W, 4Ω, 5V)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin TQFN (Thin Quad Flat No-Lead)  

### **Descriptions:**  
- The MAX9750 is a mono Class D amplifier designed for portable audio applications.  
- It features a low-power shutdown mode and a differential input to reduce noise.  
- The device includes click-and-pop suppression circuitry for improved audio performance during power-up/down.  

### **Features:**  
- **High Efficiency:** Reduces power consumption in battery-powered devices.  
- **Differential Input:** Minimizes common-mode noise.  
- **Low Quiescent Current:** 3.5mA (typical) for extended battery life.  
- **Short-Circuit and Thermal Protection:** Enhances reliability.  
- **Small Footprint:** 28-pin TQFN package saves board space.  
- **Click-and-Pop Suppression:** Improves user experience during power transitions.  

This amplifier is commonly used in smartphones, portable media players, and other compact audio devices.
