Overview

The INA210AIRSWR is a high-precision, voltage-output, current-shunt monitor designed for sensing drops across shunts at common-mode voltages from -0.3V to 26V. This zero-drift amplifier provides high accuracy with a very low offset voltage, making it suitable for both high-side and low-side current sensing applications.

Why Choose This Part

The zero-drift architecture ensures excellent stability over the full temperature range of -40 degC to 125 degC with minimal offset voltage. Its low quiescent current of 65uA makes it ideal for power-sensitive battery applications, while the tiny UQFN package saves significant PCB real estate.

Applications

Battery Management Systems
Monitoring charge and discharge currents in portable electronics and power tools to ensure safe operating limits.
Precision Power Supplies
Providing feedback loops for current-limited power delivery and overcurrent protection circuits.
Motor Control
Sensing phase currents or DC bus currents for torque control and stall detection in small motor drives.
Solar Inverters
Measuring string currents to optimize power conversion efficiency and detect panel degradation.
