It offers a -3dB bandwidth of 350 kHz and a slew rate of 2V/µs, making it suitable for DC and low-frequency AC current monitoring in power management, motor control, and battery monitoring applications. The rail-to-rail output stage allows the output to swing close to the supply rails, maximizing dynamic range when using low-voltage ADCs.
Within the same current-sense amplifier class, the INA254A1IPWAR is a zero-drift variant with a similar 350 kHz bandwidth and 2.4 V/µs slew rate, while the INA4290A2IRGVR offers a wider 1.1 MHz bandwidth and four channels in a different package. Neither is a direct pin-compatible drop-in, but both serve similar shunt-monitoring roles.
