TIINA213CQDCKRQ1
Overview
The INA213CQDCKRQ1 is an automotive-qualified, high-side or low-side voltage-output current-shunt monitor. This zero-drift amplifier can sense drops across shunts at common-mode voltages from -0.3V to 26V, independent of the supply voltage. It is AEC-Q100 qualified and functional safety-capable, making it suitable for rigorous vehicle and industrial environments.
Why Choose This Part
The zero-drift architecture ensures high accuracy with an offset voltage that remains stable over the full -40C to 125C temperature range. Its low supply current of 65uA (typical) and small SC70-6 package enable high-density power monitoring in space-constrained designs.
Applications
Key Specifications
Getting Started
To evaluate this part, use a 0.1uF bypass capacitor placed close to the V+ pin and select a shunt resistor that keeps the maximum differential input voltage within the linear range of the 50V/V gain. Standard prototype boards for SC-70 packages can be used for initial breadboarding before moving to a dedicated PCB with Kelvin connections to the shunt resistor.
