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.

Description and Introduction

High-Speed/ Precision/ G = 10 or G = 0.1 DIFFERENCE AMPLIFIERS The INA2143U is a current sense amplifier manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 2.7V to 26V  
- **Common-Mode Voltage Range:** -0.3V to +26V  
- **Gain Options:** 20 V/V, 50 V/V, 100 V/V  
- **Bandwidth:** 110 kHz (typical)  
- **Quiescent Current:** 350 µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
The INA2143U is a precision current sense amplifier designed for bidirectional current sensing applications. It provides high accuracy with low offset voltage and drift, making it suitable for power management, battery monitoring, and motor control systems.  

### **Features:**  
- Bidirectional current sensing capability  
- Low offset voltage: ±35 µV (max)  
- High common-mode rejection ratio (CMRR): 120 dB (min)  
- Wide supply and common-mode voltage range  
- Internal gain setting resistors for improved accuracy  
- Small form factor with an 8-pin SOIC package
