It operates from a 2.7 V to 20 V supply span and delivers a gain-bandwidth product of 1.3 MHz with a 2.5 V/µs slew rate. It is a current-sense amplifier, so its primary role is to amplify the voltage across a shunt resistor for load-current monitoring in power supplies, motor drives, and battery chargers.
The 1.3 MHz gain-bandwidth product sets the usable bandwidth for the current-sense signal.
The 2.7 V to 20 V supply span means this amplifier can run off a 2.7 V to 20 V supply.
The INA281B2IDBVR is offered in a SOT-23-5 package. It is surface-mount only.
