TIINA210BIDCKT

Overview

The INA210BIDCKT is a high-accuracy, zero-drift current-shunt monitor designed to sense drops across shunts at common-mode voltages from -0.3V to 26V. This voltage-output device utilizes a specialized architecture to provide a gain of 200V/V with extremely low offset voltage, ensuring precision even at low sense voltages. With a low supply current of 65uA to 100uA, it is optimized for power-sensitive monitoring in both high-side and low-side configurations.

Why Choose This Part

The zero-drift architecture enables a maximum offset voltage that allows for full-scale sensing with very low shunt values, reducing power dissipation in the sense element. It offers a wide common-mode range that is independent of the 2.7V to 26V supply voltage, providing flexibility in system design. Additionally, the SC70 package footprint is ideal for space-constrained PCB layouts while maintaining high accuracy of 1 percent.

Applications

Getting Started

To evaluate this part, engineers often use the INA210-215EVM evaluation module, which provides a pre-populated test environment for the SC70 package. When designing the PCB, place the shunt resistor as close as possible to the IN pins and use Kelvin-sense connections to minimize trace resistance errors. Ensure the 0.1uF bypass capacitor is located immediately adjacent to the V+ pin for stable operation.
