Its ±1.5% accuracy over the full -40°C to 125°C range means you can size the shunt for a 1% system error budget without over-allocating margin. The 14 kHz bandwidth is enough for DC rail monitoring, overcurrent detection, and battery-charge profiling, but not for fast-switching load transients — keep that in mind when the loop needs sub-millisecond response. ## Input common-mode range — where it sits in the circuit The input common-mode voltage spans -0.3V to 26V, so this part works on 3.3V, 5V, 12V, and 24V rails. It handles high-side sensing on a 24V supply with headroom to spare, and the -0.3V lower limit lets it read current on the low side even when the shunt drops below ground during a reverse-current event. No external level-shifter needed. ## Package and footprint — SC-70-6 layout notes Housed in a 6-pin SC-70-6, also described as 6-TSSOP / SC-88 / SOT-363. The land pattern is the standard 0.65 mm pitch SC-70 footprint. No exposed pad, so thermal dissipation is through the pins — keep the copper pour on the supply and output traces generous if the ambient runs toward the 125°C end. ## Lifecycle and sourcing posture Status is Active with ROHS3 compliance. For a BOM line that needs a zero-drift current-sense amp in SC-70-6, this part is a straightforward fit with no LTB clock ticking.","metaTitle":"INA199A2DCKT Current Sense Amplifier, ±1.5% Accuracy","metaDescription":"TI INA199A2DCKT current-sense amplifier with ±1.5% accuracy, -0.3V to 26V input range, -40°C to 125°C.
