Technical details

Its 1.1 MHz gain-bandwidth product and 2 V/µs slew rate support fast transient capture in motor-drive and solenoid-control loops, while the 15 µV input offset keeps the error budget tight for sub-10 mΩ shunts.

A 2.7 V minimum supply lets this part run from a 3.3 V rail with headroom for the cold-crank dip; the 20 V maximum covers 12 V and 24 V automotive and industrial buses without an external regulator. The 15 µV offset translates to roughly 0.15% error on a 10 mV shunt signal — good enough for a 50 A load with a 200 µΩ shunt. The 370 µA supply current is a secondary concern in most power-train designs but matters in always-on battery-monitoring nodes.

Package and mounting — SC-70-5 footprint reality

The SC-70-5 (SOT-353) package is a 5-pin surface-mount case about 2 mm × 2.1 mm.
