Single-supply current sense with 15 µV offset
The INA280A4IDCKR: Its 15 µV input offset voltage and 850 kHz gain-bandwidth product suit it for low-side or high-side sensing in motor-drive, power-management, and automotive battery-monitoring applications where the load current must be translated to a ground-referenced output voltage.
850 kHz GBW — bandwidth for switching loops
The 850 kHz gain-bandwidth product gives the INA280A4IDCKR enough closed-loop bandwidth to track current waveforms in buck or boost converters switching at a few hundred kilohertz, or to capture the envelope in a brushed DC motor start-up. The 2 V/µs slew rate keeps the output from lagging on fast current edges, though the 20 µA input bias current means the shunt value should be kept low enough that the bias drop does not eat into the measurement headroom.
