Description and Introduction

2.3W, Ultra-Low-EMI, Filterless, Class D Audio Amplifier The MAX9705DETB+T is a Class D audio amplifier manufactured by Maxim Integrated. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Power:** Up to 2.8W into 4Ω at 5V supply  
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Efficiency:** Up to 90%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.04% (1W into 4Ω, 5V)  
- **Signal-to-Noise Ratio (SNR):** 95dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin TDFN (3mm x 3mm)  

### **Descriptions:**  
- The MAX9705DETB+T is a mono, filterless Class D amplifier designed for portable audio applications.  
- It features a low-power shutdown mode and requires minimal external components.  
- The amplifier operates in a bridge-tied load (BTL) configuration, eliminating the need for an output coupling capacitor.  

### **Features:**  
- **Filterless Operation:** Reduces external component count.  
- **Low Quiescent Current:** 3.5mA (typical)  
- **Click-and-Pop Suppression:** Minimizes audible noise during power-up/down.  
- **Short-Circuit and Thermal Protection:** Enhances reliability.  
- **Small Footprint:** Suitable for space-constrained designs.
