TIINA214BIDCKR
Overview
The INA214BIDCKR 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 bi-directional amplifier features a fixed gain of 100V/V and a low quiescent current of 100uA, making it ideal for power-sensitive monitoring applications.
Why Choose This Part
The zero-drift architecture ensures high accuracy with minimal offset over the full -40C to 125C temperature range. Its wide common-mode range allows for both high-side and low-side sensing, while the SC70 package offers a minimal PCB footprint for dense electronic assemblies.
Applications
Key Specifications
Getting Started
To evaluate this part, use a shunt resistor sized for your maximum expected current and the 100V/V gain to ensure the output stays within your ADC range. Ensure the REF pin is tied to ground for unidirectional sensing or to a mid-supply reference for bidirectional measurement.
