Product details

Current sense amp in a five-pin SOT

The INA281B2IDBVT: Gain bandwidth is 1.3 MHz, with a slew rate of 2.5V/µs — fast enough to capture current transients in a switching regulator output or a motor phase leg without the output lagging behind the shunt voltage. Operating temperature range is -40°C to 125°C, covering under-hood and industrial enclosure environments.
