- **Part Number:** INA208AIDGST  
- **Package/Case:** MSOP-8  
- **Operating Temperature Range:** -40°C to +125°C  
- **Supply Voltage Range:** 2.7V to 18V  
- **Common-Mode Voltage Range:** -0.3V to +26V  
- **Bandwidth:** 500kHz  
- **Gain Options:** 20V/V, 50V/V, 100V/V  
- **Quiescent Current:** 900µA (typical)  
- **Input Offset Voltage:** ±150µV (max)  
- **Output Type:** Rail-to-Rail  

### **Descriptions:**
The INA208AIDGST is a precision current-sense amplifier designed for high-side or low-side current measurement. It provides accurate amplification of small differential voltages across a shunt resistor, making it suitable for applications such as power management, battery monitoring, and motor control.  

### **Features:**
- **Wide Input Common-Mode Range:** Supports -0.3V to +26V, independent of supply voltage.  
- **Adjustable Gain:** Available in fixed gain options (20V/V, 50V/V, 100V/V).  
- **Low Offset Voltage:** Ensures high accuracy in current sensing.  
- **Rail-to-Rail Output:** Allows full utilization of the supply range.  
- **Low Quiescent Current:** Enhances power efficiency.  
- **High Bandwidth (500kHz):** Suitable for dynamic current measurements.  
- **Robust Protection:** Includes overvoltage and reverse-voltage protection.  

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

Application Scenarios & Design Considerations

80V, Low- or High-side, High-Speed, Voltage Out Current Shunt Monitor with Window Comparator & Ref 10-VSSOP -40 to 125

Alternative Part Number

  • INA219AIDCNR --: Same INA2xx current/power monitor family with I2C interface and similar functionality; different package (SOT-23) but widely available and often used as a drop-in for current sensing designs.
  • INA226AIDGSR --: High-side current/power monitor with I2C in the same DGS (VSSOP) package, offering comparable accuracy and features, making it a strong functional substitute.
  • ACS712ELCTR-20A-T --: Hall-effect current sensor providing isolated current measurement as an alternative sensing approach when the INA208 is unavailable, though it requires different circuit design.
