Description and Introduction

Ultra-Low-Power, Open-Drain, Single/Dual-Supply Comparators The MAX974CSE+ is a Class D audio amplifier manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX974CSE+  
- **Type:** Class D Audio Amplifier  
- **Output Power:** Up to 20W (depends on supply voltage and load impedance)  
- **Supply Voltage Range:** 4.5V to 14V  
- **Efficiency:** Up to 87%  
- **THD+N (Total Harmonic Distortion + Noise):** Typically 0.04%  
- **Signal-to-Noise Ratio (SNR):** >90dB  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 16-pin SOIC (CSE suffix)  

### **Descriptions:**  
The MAX974CSE+ is a high-efficiency, Class D audio amplifier designed for portable and battery-powered applications. It integrates a stereo bridge-tied load (BTL) output stage, eliminating the need for external output coupling capacitors. The amplifier features a fixed gain and requires minimal external components, making it suitable for space-constrained designs.

### **Features:**  
- **High Efficiency:** Up to 87% efficiency reduces power consumption and heat dissipation.  
- **Low Quiescent Current:** Typically 4mA (shutdown mode: <1µA).  
- **Pop-and-Click Suppression:** Minimizes audible noise during power-up/down.  
- **Thermal and Short-Circuit Protection:** Built-in safeguards protect the device from damage.  
- **Single-Supply Operation:** Works with a supply voltage from 4.5V to 14V.  
- **Fixed Gain:** Simplifies design by eliminating the need for gain-setting resistors.  
- **Small Footprint:** 16-pin SOIC package saves board space.  

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