TIINA214AIDCKR

Overview

The INA214AIDCKR is a high-side or low-side current-shunt monitor that can sense drops across shunts at common-mode voltages from -0.3V to 26V, independent of the supply voltage. It features a zero-drift architecture that provides high accuracy with a maximum gain error of 0.5 percent and an extremely low offset. This device is particularly effective for power management and battery monitoring where precise current measurement is required in a small footprint.

Why Choose This Part

The zero-drift technology ensures high precision across the entire -40C to 125C operating range while consuming only 65uA of typical supply current. Its ability to handle common-mode voltages up to 26V regardless of the 2.7V to 26V supply voltage offers significant flexibility for various rail voltages.

Applications

Getting Started

To evaluate this part, use the INA214EVM evaluation module which provides a pre-populated SC70 footprint and test points for quick prototyping. Ensure the shunt resistor is placed close to the IN+ and IN- pins to minimize trace resistance errors and inductive pickup.
