Its 1.3 MHz bandwidth and 2.5 V/µs slew rate let it track fast current edges in PWM-driven loads like motor windings or solenoid valves without significant phase lag. The 2.7 V to 20 V supply span means it can run directly from a 3.3 V MCU rail, a 5 V logic supply, or a 12 V/24 V industrial bus — no extra regulator needed. ## Bandwidth, offset, and drive capability The 1.3 MHz -3 dB bandwidth is roughly 4× wider than the 350 kHz of the INA254A1IPWAR, making the INA310A2IDGKR a better fit for applications that need to capture sub-microsecond current spikes — think overcurrent detection in fast-switching DC-DC converters or BLDC motor commutation events. Input offset voltage is trimmed to 15 µV typical, a direct benefit of the Zero-Drift architecture. At a 1 mΩ shunt, that offset translates to 15 mA of apparent current error — negligible for most 10 A+ loads, but worth noting if you're measuring standby currents below 100 mA. Supply current is 1.6 mA typical, low enough to be powered from a GPIO pin if the MCU can source that much. The single-ended output drives directly into an ADC input without a buffer. ## Package, rework, and lifecycle It comes in an 8-VSSOP package — a 3.00 mm × 3.00 mm body, 0.65 mm pitch. The small footprint saves board space, and the exposed pad (if present on the VSSOP variant) helps thermal transfer to the PCB copper. For a rework tech: the 0.65 mm pitch is hand-solderable with a fine tip and flux, but a hot-air station set to 300°C with a small nozzle makes removal clean. The part is small enough that the pad copper area under the package matters more than the package itself for heat sinking. ## Sourcing and ordering Active lifecycle means no end-of-life risk for ongoing production.
