Overview

The INA215AIDCKT is a voltage-output, high-side or low-side current-shunt monitor designed for precision current sensing. It utilizes a zero-drift architecture to provide high accuracy with a common-mode range extending from -0.3V up to 26V, independent of the supply voltage.

Why Choose This Part

The device features an exceptionally low supply current of 65uA (typical) and a zero-drift architecture that ensures 0.5 percent accuracy across the temperature range. Its SC-70-6 package offers a significant footprint reduction for space-constrained designs while supporting wide common-mode voltages up to 26V.

Applications

Battery Management Systems
Monitoring charge and discharge cycles in portable electronics and power tools with minimal power overhead.
Power Supply Monitoring
Real-time current measurement for overcurrent protection and power consumption logging in industrial equipment.
Motor Control
Phase current sensing in low-voltage motor drives to improve torque control and fault detection.
Telecom Infrastructure
Precise current monitoring in high-density line cards where small form factors are required.
