Frequently Asked Questions
What is the common-mode voltage range of the INA214AIRSWR?
The INA214AIRSWR supports a common-mode voltage range up to 26V, allowing it to be used for both low-side and high-side current sensing applications. This wide range makes it suitable for 12V, 15V, and 24V power rails commonly found in industrial and automotive systems.
What is the CMRR specification of the INA214AIRSWR?
The INA214AIRSWR achieves a minimum CMRR of 105dB and a typical CMRR of 140dB. This exceptional common-mode rejection ratio, enabled by the zero-drift architecture, ensures accurate current measurements even in the presence of high common-mode noise or voltage fluctuations on the power rail.
What package is the INA214AIRSWR available in and what are its dimensions?
The INA214AIRSWR is available in a small WSON (UQFN) surface-mount package, suitable for compact PCB layouts. The 'R' suffix indicates tape-and-reel packaging, making it compatible with automated pick-and-place assembly for high-volume production.
Can the INA214AIRSWR measure current in both directions?
Yes, the INA214AIRSWR is a bi-directional current sense amplifier capable of measuring both positive and negative current flow. This makes it ideal for battery charge/discharge monitoring, regenerative motor drives, and any application where bidirectional power flow measurement is required.
