Description and Introduction

microPower, Single-Supply, CMOS NTATION AMPLIFIER The **INA322EA** is a **current shunt and power monitor** manufactured by **Texas Instruments (TI)**. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage (V+):** 3.0V to 26V  
- **Common-Mode Voltage Range:** -0.3V to +26V  
- **Current Sense Inputs:** Three independent channels  
- **ADC Resolution:** 12-bit  
- **Shunt Voltage Range:** ±163.84mV (programmable full-scale range)  
- **Bus Voltage Range:** 0V to 26V  
- **Accuracy (Max):**  
  - Shunt Voltage: ±0.5% (typical)  
  - Bus Voltage: ±0.2% (typical)  
- **Interface:** I²C-compatible (up to 400kHz)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-pin TSSOP  

### **Descriptions:**
- The **INA322EA** is a **three-channel, high-side current and bus voltage monitor** with an **I²C interface**.  
- It provides **simultaneous monitoring of shunt voltage drops and bus supply voltages** for three separate power rails.  
- Designed for **precision current and power measurement** in applications such as servers, telecom equipment, and power management systems.  

### **Features:**
- **Three Independent Current-Sensing Channels**  
- **Wide Common-Mode Voltage Range** (independent of supply voltage)  
- **Programmable Alert Function** for overcurrent, undervoltage, and overvoltage conditions  
- **Low-Drift Internal Voltage Reference** (10ppm/°C typical)  
- **Power Consumption:** 700µA (typical)  
- **Programmable Conversion Averaging** for noise reduction  
- **Compatible with 1.8V, 3.3V, and 5V I²C Logic Levels**  

This information is strictly based on TI's datasheet and product documentation for the **INA322EA**.
