For a 10 mV shunt step, the output rises at 2V/µs, reaching full scale in about 5 µs. This is adequate for monitoring switching power-supply outputs or motor-phase currents at PWM frequencies up to a few hundred kilohertz, but not for sub-microsecond fault detection. The 20 µA input bias current is a consideration when the shunt value is high — a 10 mΩ shunt drops only 200 µV per amp, so the 2 µV offset dominates error, not bias current.","metaTitle":"INA290A5IDCKR Current Sense Amplifier, 800 kHz Bandwidth","metaDescription":"TI INA290A5IDCKR current sense amplifier: 2.7 V to 20 V supply, 800 kHz bandwidth, 2 µV offset, SC-70-5.
