The INA211CIDCKT from Texas Instruments is a precision current shunt monitor that offers industry-leading performance for system monitoring of power supply current, battery management, and portable devices. This high-side current sensing device operates over a wide input voltage range from 2.7V to 26V and is capable of bidirectional current sensing.

Key Features

• High Accuracy: The INA211CIDCKT features a zero-drift architecture, providing a low offset voltage and enabling high-accuracy current measurements across a wide temperature range, making it ideal for precision applications.
• Wide Input Common-Mode Voltage Range: Designed for high-side current sensing, this device can handle common-mode voltages from 2.7V up to 26V, independent of the supply voltage.
• Low Quiescent Current: The device is optimized for power-sensitive applications with a quiescent current of only 100µA (typical), which helps in reducing the overall power consumption of the system.
• Small Footprint: Packaged in a compact, 6-pin SC-70 package, the INA211CIDCKT takes up minimal board space, making it perfect for space-constrained applications.
• Output Voltage: It provides a voltage output that increases with increasing current flowing through the shunt resistor, allowing for easy interfacing with any typical analog-to-digital converter (ADC).
