Technical details

Precision current sensing in a tiny footprint

The 800 kHz bandwidth and 2V/µs slew rate support fast load-transient capture, while the 2 µV input offset voltage enables accurate readings at low shunt drops.

Bandwidth and slew rate — what they mean for transient response

The 800 kHz -3 dB bandwidth and 2V/µs slew rate together define the amplifier's ability to track fast current changes. For a 10 mV shunt step, the output rises at 2V/µs, reaching full scale in about 5 µs. 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.
