Description and Introduction

Precision, High-Side Current-Sense Amplifiers The MAX471ESA is a precision, high-side current-sense amplifier manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
Maxim Integrated (now part of Analog Devices)  

### **Specifications:**  
- **Supply Voltage Range:** +3V to +36V  
- **Input Common-Mode Voltage Range:** +3V to +36V  
- **Current-Sense Gain:** 500V/V (fixed)  
- **Bandwidth:** 15kHz (typical)  
- **Quiescent Supply Current:** 60µA (typical)  
- **Output Voltage Swing:** 0.5V below V+ (with 10kΩ load)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (ESA)  

### **Descriptions:**  
- The MAX471ESA is a high-side current-sense amplifier designed for monitoring current in battery-powered systems, power supplies, and motor control applications.  
- It provides a ground-referenced output proportional to the load current, eliminating the need for a low-side shunt resistor.  
- The device operates over a wide supply voltage range and is optimized for low-power applications.  

### **Features:**  
- **High-Side Current Sensing:** Eliminates ground disturbances.  
- **Wide Input Voltage Range:** Supports operation from +3V to +36V.  
- **Low Quiescent Current:** Consumes only 60µA (typical).  
- **Fixed Gain of 500V/V:** Simplifies design by eliminating external gain-setting resistors.  
- **Ground-Referenced Output:** Compatible with ADCs and microcontrollers.  
- **Small Footprint:** Available in an 8-pin SOIC package.

Description and Introduction

Precision, High-Side Current-Sense Amplifiers The MAX471ESA is a precision, high-side current-sense amplifier manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX471ESA  
- **Package:** 8-SOIC  
- **Operating Voltage Range:** +3V to +36V  
- **Supply Current:** 60µA (typical)  
- **Gain Accuracy:** ±1.5% (max)  
- **Bandwidth:** 500kHz (typical)  
- **Common-Mode Input Range:** 0V to 36V  
- **Output Voltage Swing:** Rail-to-Rail  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX471ESA is a precision, high-side current-sense amplifier designed for monitoring current in battery-powered systems, power supplies, and other applications requiring accurate current measurement. It integrates a precision amplifier with a low offset voltage, enabling accurate current sensing across a wide input range.  

### **Features:**  
- High-side current sensing  
- Wide input voltage range (3V to 36V)  
- Low quiescent current (60µA)  
- Rail-to-rail output swing  
- ±1.5% gain accuracy  
- 500kHz bandwidth  
- No external sense resistor required (internal 35kΩ resistor)  
- Small 8-pin SOIC package  

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