What this current sense amplifier brings to the rail
The 800 kHz gain-bandwidth product and 2 V/µs slew rate let it track fast load steps — useful for overcurrent detection in motor drives or DC-DC converter output monitoring.
The 2.7 V minimum supply means this part works through cold-crank conditions on a 3.3 V rail, and the 20 V maximum covers 12 V and 15 V industrial buses with margin. If your design lives inside a temperature-controlled rack, the same part still fits, but the extended range is what you pay for when the environment is not forgiving.
No exposed thermal pad to stitch, so the layout is straightforward: decouple the supply pin with a 0.1 µF ceramic close to the pin, and keep the sense traces short and Kelvin-connected to the shunt resistor.
For production programs that need a multi-year sourcing horizon, this part carries no imminent obsolescence risk. The ROHS3 compliance covers the current EU exemption set, so it ships into European builds without a waiver.
