Description and Introduction

Ultra-Low-Power / Open-Drain / Single/Dual-Supply Comparators The MAX974ESE is a stereo audio power amplifier IC manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX974ESE  
- **Type:** Stereo Audio Power Amplifier  
- **Package:** 16-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage Range:** 4.5V to 14V  
- **Output Power:** Up to 2.5W per channel (into 4Ω at 5V supply)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.04% (typical)  
- **Signal-to-Noise Ratio (SNR):** 90dB (typical)  
- **Efficiency:** Up to 90% (Class D operation)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
The MAX974ESE is a Class D stereo audio power amplifier designed for portable and battery-powered applications. It provides high efficiency and low power consumption, making it suitable for devices like smartphones, tablets, and portable speakers. The amplifier features a differential input and requires minimal external components for operation.

### **Features:**
- **Class D Operation:** High efficiency for longer battery life.  
- **Low Quiescent Current:** Reduces power consumption.  
- **Click-and-Pop Suppression:** Minimizes audible noise during power-up/down.  
- **Thermal and Short-Circuit Protection:** Enhances reliability.  
- **Differential Inputs:** Reduces common-mode noise.  
- **Small Footprint:** 16-pin SOIC package for space-constrained designs.  
- **Wide Supply Voltage Range:** Supports operation from 4.5V to 14V.  

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

Application Scenarios & Design Considerations

Ultra-Low-Power / Open-Drain / Single/Dual-Supply Comparators

Alternative Part Number

  • LT1016CS8 --: Fast comparator in SO-8 with similar supply range and pinout, widely used as a MAX974 substitute.
  • TL714CP --: High-speed comparator with comparable response time and open-collector output, available in DIP-8.
  • ADCMP600BRJZ --: Modern high-speed comparator with similar threshold and propagation characteristics, suitable for replacement designs.
  • LTC1540CS8 --: Pin-compatible comparator in SO-8 with similar supply range and response time, widely available from the Linear Technology line.
  • TLV3201AIDBVR --: Low-power comparator with comparable propagation delay and rail-to-rail inputs, suitable drop-in for many MAX974 applications.
  • LM393DR --: Industry-standard dual comparator in SO-8, lower cost and broad availability, acceptable when dual-channel and relaxed speed are tolerable.
