Frequently Asked Questions
What is the common-mode voltage range of the INA212BQDCKRQ1?
The INA212BQDCKRQ1 supports a common-mode voltage range up to 26V, allowing it to be used for high-side current sensing in 12V and 24V automotive electrical systems without requiring level shifting.
Is the INA212BQDCKRQ1 AEC-Q100 qualified for automotive use?
Yes, the INA212BQDCKRQ1 is AEC-Q100 qualified, making it suitable for automotive applications such as battery management systems, motor drives, and power distribution modules that require high reliability over wide temperature ranges.
What is the CMRR of the INA212BQDCKRQ1 and why does it matter?
The INA212BQDCKRQ1 provides a minimum CMRR of 105dB and a typical CMRR of 140dB. High CMRR ensures the amplifier accurately measures small differential voltages across a shunt resistor while rejecting large common-mode voltages present in automotive power lines.
Can the INA212BQDCKRQ1 measure both charging and discharging current?
Yes, the INA212BQDCKRQ1 is bi-directional, meaning it can accurately measure current flowing in both directions. This makes it well-suited for battery pack monitoring where both charge and discharge currents must be tracked.
What package does the INA212BQDCKRQ1 come in?
The INA212BQDCKRQ1 is available in a SOT-23 6-pin package, which is a compact surface-mount form factor ideal for space-constrained automotive PCB designs.
