At 1 MHz bandwidth, the part can track current changes in switching regulators and motor drives. The 2.5 V/µs slew rate supports feeding a comparator or ADC input.
The SOT-23-5 footprint is a standard surface-mount package. The part is available on Tape & Reel or Cut Tape.
The -3 dB bandwidth is 1 MHz, with a slew rate of 2.5 V/µs. This is suitable for switching power supply and motor drive current feedback loops.
A close functional peer is the INA254A1IPWAR, also a single-channel current-sense amplifier with zero-drift architecture, 350 kHz bandwidth, 2.4 V/µs slew rate, and the same 2.7 V minimum supply and -40°C to 125°C range. The INA4290A2IRGVR is a quad-channel option with 1.1 MHz bandwidth and 2 V/µs slew rate. Neither is a direct pin-for-pin replacement; verify the pinout and package before substituting.
