Frequently Asked Questions
What is the supply voltage range of the INA211AIDCKT?
The INA211AIDCKT operates with a supply voltage up to 26V maximum, with a nominal supply voltage of 12V (Vsup). This wide range supports both 12V automotive systems and 24V industrial bus architectures, making it versatile for a broad range of power monitoring applications.
Can the INA211AIDCKT be used for high-side current sensing in automotive applications?
Yes, the INA211AIDCKT is specifically designed for both high-side and low-side current sensing. It carries an automotive temperature grade and meets AEC-Q100 requirements, making it suitable for battery management, motor drives, and safety-critical automotive power circuits operating up to 26V.
What package does the INA211AIDCKT come in and what are the pin pitch details?
The INA211AIDCKT is housed in a SOT23 6-pin (DCK) surface-mount package with a 0.65mm terminal pitch and dual gull-wing terminal form. This compact footprint is ideal for space-constrained designs, and the matte tin (Sn) finish ensures compatibility with standard lead-free soldering processes.
What does 'zero-drift' mean in the context of the INA211AIDCKT?
Zero-drift refers to a circuit technique that continuously corrects offset voltage errors, ensuring the INA211AIDCKT maintains high measurement accuracy over temperature and time. This is critical in automotive and industrial applications where thermal variations could otherwise introduce significant current measurement errors across the shunt resistor.
