### **Descriptions:**  
The INA2321EA/250 is a high-precision digital current and power monitor with an integrated 16-bit delta-sigma ADC. It provides accurate measurements of current, voltage, and power consumption in low-side or high-side configurations. The device supports bidirectional current sensing and communicates via an I²C interface.  

### **Features:**  
- **High Accuracy:** ±1% current measurement error (max)  
- **Wide Input Range:** Supports bus voltages up to 36V  
- **Low Shunt Voltage Drop:** Enables minimal power loss  
- **Programmable Alert Function:** Configurable thresholds for overcurrent/undervoltage detection  
- **Low Power Consumption:** Optimized for energy-efficient applications  
- **Integrated ADC:** 16-bit resolution for precise measurements  
- **I²C Interface:** Supports standard (100kHz) and fast (400kHz) modes  

This device is commonly used in power management, battery monitoring, and industrial control systems.

Application Scenarios & Design Considerations

Micropower single-supply CMOS Instrumentation Amplifier

Alternative Part Number

  • MAX4420ESA+ --: High-speed current-sense amplifier with similar function and supply range; different series and pin-compatible class for current monitoring applications.
  • AD8210YRZ --: High common-mode voltage current shunt amplifier offering comparable gain and bandwidth, suitable as a functional replacement in current-sense designs.
  • LT6105IMS8#PBF --: Precision current-sense amplifier with wide input common-mode range and adjustable gain, a viable alternative when the original is unavailable.
