Overview

The INA210AIDCKT is a high-precision, zero-drift current-shunt monitor designed to sense drops across shunts at common-mode voltages from -0.3V to 26V. This voltage-output, current-sense amplifier features a fixed gain of 200V/V and is capable of sensing current in both directions regardless of the supply voltage.

Why Choose This Part

The device offers exceptional accuracy with an offset voltage that remains stable over time and temperature due to its zero-drift architecture. Its low power consumption of 65uA (typical) and very small SC-70 footprint make it ideal for space-constrained, battery-operated devices.

Applications

Power Management
Monitoring rail currents in computing and telecommunications equipment to manage power distribution efficiency.
Battery Charging and Discharging
Precise tracking of current flow into and out of battery packs for state-of-charge calculations.
Motor Control
Feedback sensing in low-side or high-side motor drive circuits to implement overcurrent protection and torque control.
Precision Current Sources
Acting as the feedback element in closed-loop systems requiring highly stable current regulation.

Getting Started

To evaluate this part, use the INA210-215EVM evaluation module which provides a pre-populated PCB for quick testing. When designing your PCB, place the shunt resistor as close as possible to the IN+ and IN- pins and use Kelvin-sense connections to minimize trace resistance errors.
