TIINA225AIDGKR
Overview
The INA225AIDGKR is a high-side voltage-output current shunt monitor with a zero-drift architecture and four selectable gain settings. It operates over a wide common-mode voltage range of 2.7V to 36V, making it suitable for monitoring current in both low-voltage and industrial power systems. The device simplifies design by integrating a programmable gain amplifier, requiring only an external shunt resistor for operation.
Why Choose This Part
The zero-drift architecture ensures high accuracy with a maximum error of 0.15 percent across the operating temperature range. Its integrated programmable gain (25V/V, 50V/V, 100V/V, 200V/V) allows for flexible scaling of different shunt resistor values without changing external components.
Applications
Key Specifications
Getting Started
To evaluate the INA225, engineers can utilize the INA225EVM evaluation module to test performance with different shunt configurations. Design requires connecting the GS0 and GS1 pins to either GND or VS to select the desired gain, and placing a precision shunt resistor in the high-side load path.
