Description and Introduction

High-Speed/ Precision/ G = 10 or G = 0.1 DIFFERENCE AMPLIFIERS The INA2143U is a precision current shunt monitor manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** INA2143U  
- **Type:** Current Shunt Monitor  
- **Supply Voltage Range:** 2.7V to 26V  
- **Common-Mode Voltage Range:** -0.3V to +26V  
- **Gain Options:** Fixed gains (e.g., 50 V/V, 100 V/V, 200 V/V, etc., depending on variant)  
- **Bandwidth:** Typically 100 kHz (varies by gain)  
- **Quiescent Current:** Typically 100 µA  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The INA2143U is a high-side or low-side current shunt monitor that provides accurate current sensing by measuring the voltage drop across a shunt resistor. It is designed for applications requiring precision current measurement, such as power management, battery monitoring, and motor control.  

### **Features:**  
- **Wide Input Voltage Range:** Supports operation from 2.7V to 26V  
- **High Common-Mode Voltage Range:** -0.3V to +26V  
- **Low Offset Voltage:** Ensures accurate current measurement  
- **Fixed Gain Options:** Eliminates the need for external gain-setting resistors  
- **Low Quiescent Current:** Reduces power consumption  
- **High Accuracy:** Suitable for precision applications  
- **Small Form Factor:** Available in an SOIC-8 package  

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