Description and Introduction

High-Speed, Precision, G = 10 or G = 0.1 Difference Amplifiers 14-SOIC -55 to 125 The **INA2143UG4** is a current sense amplifier manufactured by **Texas Instruments (TI)/Burr-Brown (BB)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)/Burr-Brown (BB)  
- **Category:** Integrated Circuits (ICs) - Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps  
- **Package:** 14-SOIC  
- **Operating Temperature Range:** -40°C to +125°C  
- **Supply Voltage Range:** 2.7V to 26V  
- **Common-Mode Voltage Range:** -0.3V to +26V  
- **Gain Options:** Fixed (e.g., 20V/V, 50V/V, 100V/V, etc., depending on variant)  
- **Bandwidth:** Typically 100kHz (varies by gain)  
- **Quiescent Current:** Typically 500µA  
- **Input Offset Voltage:** Low (typically <100µV)  
- **Output Type:** Rail-to-Rail  

### **Descriptions:**  
- The **INA2143UG4** is a precision current sense amplifier designed for high-side or low-side current sensing.  
- It provides accurate current measurements by amplifying small differential voltages across a shunt resistor.  
- It is suitable for applications requiring high common-mode voltage tolerance and low power consumption.  

### **Features:**  
- **Wide Common-Mode Voltage Range:** Supports operation from -0.3V to +26V, independent of supply voltage.  
- **Low Offset Voltage:** Ensures high accuracy in current sensing.  
- **Fixed Gain Options:** Eliminates the need for external gain-setting resistors.  
- **Low Quiescent Current:** Optimized for power-sensitive applications.  
- **Rail-to-Rail Output:** Allows full-scale output swing close to supply rails.  
- **Robust Protection:** Includes overvoltage and reverse polarity protection.  

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