Description and Introduction

High-Speed, Micropower, Low-Voltage, SOT23, Rail-to-Rail I/O Comparators The MAX991EUA-T is a precision, high-side current-sense amplifier manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage Range:** +2.7V to +28V  
- **Input Common-Mode Voltage Range:** +2.7V to +28V  
- **Gain Accuracy:** ±0.5% (max)  
- **Gain Options:** 25V/V, 50V/V, 100V/V  
- **Bandwidth:** 500kHz (typical)  
- **Quiescent Current:** 85µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (UA)  

### **Description:**  
The MAX991EUA-T is a high-side current-sense amplifier designed for precision current measurement in applications such as battery monitoring, power management, and motor control. It operates with a wide input common-mode voltage range and provides accurate amplification of small differential voltages across a shunt resistor.

### **Features:**  
- **High-Side Current Sensing:** Eliminates ground disturbances.  
- **Wide Input Common-Mode Range:** Supports operation up to +28V.  
- **Low Quiescent Current:** 85µA (typical) for power efficiency.  
- **Fixed Gain Options:** 25V/V, 50V/V, or 100V/V.  
- **Low Offset Voltage:** ±100µV (max) for high accuracy.  
- **Small Package:** 8-pin µMAX for space-constrained designs.  
- **Reverse Battery Protection:** Tolerates -5V to +28V on input pins.
