TIINA199A1DCKR
Overview
The INA199A1DCKR is a zero-drift, voltage-output current-shunt monitor designed for bidirectional current sensing. It can sense drops across shunts at common-mode voltages from -0.3V to 26V, independent of the supply voltage. The device operates on a low quiescent current of 100uA and provides a fixed gain of 50V/V.
Why Choose This Part
The zero-drift architecture allows for high accuracy with a 1.5 percent maximum gain error across the full temperature range of -40C to 125C. Its small SC70 package and low 100uA current consumption make it ideal for space-constrained, battery-powered applications.
Applications
Key Specifications
Getting Started
To evaluate this part, use a high-precision shunt resistor matched to your maximum expected current and the 50V/V gain. Ensure the REF pin is tied to ground for unidirectional sensing or to a mid-supply voltage for bidirectional monitoring. Texas Instruments offers the INA199EVM evaluation module for rapid prototyping.
