TIINA211BIDCKT
Overview
The INA211BIDCKT is a high-side, voltage-output, current-shunt monitor designed for precision current sensing. It features a zero-drift architecture that provides high accuracy with a common-mode range of -0.3V to 26V, independent of the supply voltage. With a low supply current of 65uA to 100uA, it is optimized for power-sensitive applications where accurate current measurement is required.
Why Choose This Part
The zero-drift architecture minimizes offset voltage and drift over temperature, ensuring consistent performance from -40C to 125C. Its wide common-mode range allows for high-side sensing even when the system voltage exceeds the amplifier supply voltage. The SC-70 package offers an extremely small footprint for dense PCB layouts.
Applications
Key Specifications
Getting Started
When designing with the INA211, place a 0.1uF bypass capacitor as close to the supply pin as possible and use Kelvin connections for the shunt resistor to maximize accuracy. For evaluation, use the INA211EVM breakout board to test performance in your specific circuit conditions. Ensure the shunt resistor is sized so the maximum differential input voltage does not exceed the linear output range at your chosen supply voltage.
