Description and Introduction

1.2W, Low-EMI, Filterless, Class D Audio Amplifier The MAX9700DETB+T is a Class D audio power amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Part Number:** MAX9700DETB+T  
- **Type:** Class D Audio Power Amplifier  
- **Output Power:** Up to 20W (into 4Ω at 10% THD+N, 12V supply)  
- **Supply Voltage Range:** 4.5V to 14V  
- **Efficiency:** Up to 87%  
- **THD+N (Total Harmonic Distortion + Noise):** 0.04% (typical at 1W into 4Ω)  
- **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 MAX9700DETB+T is a high-efficiency, mono Class D amplifier designed for audio applications.  
- It features a fixed gain of 20dB (10V/V) and does not require an output filter when driving a speaker.  
- The device operates in a single-ended or bridge-tied load (BTL) configuration.  
- It includes click-and-pop suppression circuitry to minimize audible noise during power-up and shutdown.  

### **Features:**
- **Filterless Operation:** Eliminates the need for bulky external LC filters.  
- **Low EMI (Electromagnetic Interference):** Spread-spectrum modulation reduces EMI.  
- **Thermal and Short-Circuit Protection:** Built-in safeguards for reliability.  
- **Low Quiescent Current:** 4mA (typical) for power efficiency.  
- **Shutdown Mode:** Reduces power consumption when not in use.  
- **Small Footprint:** 10-pin TDFN package saves board space.  

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