The 40 kHz GBW sets the usable bandwidth for the current loop — fast enough for overcurrent detection and load monitoring, but not for switching-frequency ripple capture above a few hundred kHz. The 65 µA supply current keeps the quiescent draw low in always-on sense paths. Input offset voltage of 1 µV and input bias current of 28 µA are typical for a shunt-based sense amp; the offset translates to a DC error at the output that the designer budgets into the trip threshold.

Product details
Frequently asked questions
What is the gain bandwidth product of INA215AIDCKR?
The gain-bandwidth product is 40 kHz, which defines the usable frequency range for current sensing — adequate for DC and low-frequency AC monitoring.
What are the alternatives for INA215AIDCKR?
The INA4290A2IRGVR is a four-channel current-sense amplifier with a 1.1 MHz GBW and 2 V/µs slew rate, offering wider bandwidth and more channels for multi-rail monitoring. The INA254A1IPWAR is a zero-drift single-channel part with 350 kHz GBW and 2.4 V/µs slew rate, suited for precision low-drift applications. Neither is a direct pin-for-pin replacement; check the package and pinout before substituting.
