Description and Introduction

High-Speed/ Precision/ G = 10 or G = 0.1 DIFFERENCE AMPLIFIERS The INA2143UA is a high-side current shunt monitor manufactured by Texas Instruments (TI) and Burr-Brown (BB).  

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 26V  
- **Common-Mode Voltage Range:** -0.3V to +26V  
- **Gain Options:**  
  - INA2143UA: Fixed gain of 100 V/V  
- **Accuracy:**  
  - Gain Error: ±0.5% (max)  
  - Offset Voltage: ±100 µV (max)  
- **Bandwidth:** 500 kHz  
- **Quiescent Current:** 900 µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The INA2143UA is a precision current shunt monitor that measures voltage across a shunt resistor and provides an amplified output proportional to the current. It is designed for high-side sensing in applications such as power management, battery monitoring, and motor control.  

### **Features:**  
- Wide input common-mode voltage range  
- High accuracy with low offset and gain error  
- Bidirectional current sensing capability  
- Internal gain eliminates need for external resistors  
- Low quiescent current for power-sensitive applications  
- Robust design with reverse polarity protection  

For detailed datasheets, refer to TI/BB official documentation.
