Description and Introduction

2.6W Stereo Audio Power Amplifiers and DirectDrive® Headphone Amplifiers The MAX9755ETI+T is a Class D audio power amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX9755ETI+T  
- **Package:** 28-TQFN-EP (5x5mm)  
- **Operating Voltage Range:** 4.5V to 14V  
- **Output Power:**  
  - 2.6W per channel into 4Ω (at 5V supply, THD+N = 1%)  
  - 1.4W per channel into 8Ω (at 5V supply, THD+N = 1%)  
- **Efficiency:** Up to 90% (Class D operation)  
- **Signal-to-Noise Ratio (SNR):** >95dB (A-weighted)  
- **Total Harmonic Distortion + Noise (THD+N):** <0.1% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The MAX9755ETI+T is a stereo Class D audio amplifier designed for portable and battery-powered applications. It integrates two high-efficiency Class D amplifiers with a spread-spectrum modulation scheme to reduce EMI. The device includes features such as thermal and short-circuit protection, making it suitable for space-constrained designs requiring high-quality audio output.

### **Features:**  
- **Stereo Class D Amplifier:** Two independent channels.  
- **Low Quiescent Current:** 4.5mA (typical) per channel.  
- **Spread-Spectrum Modulation:** Reduces EMI emissions.  
- **Thermal & Short-Circuit Protection:** Enhances reliability.  
- **Click-and-Pop Suppression:** Minimizes audible noise during power-up/down.  
- **Shutdown Mode:** Ultra-low power consumption (<1µA).  
- **Small Footprint:** 28-pin TQFN package (5mm x 5mm).  

This information is strictly based on the manufacturer's datasheet and technical documentation.
