It handles common-mode voltages from -0.3 V up to 26 V. ## Package and hand-solderability The INA199A3DCKT comes in an SC-70-6 package — that's the six-lead variant of the SOT-363 footprint. ## Temperature range and environment Rated for -40°C to 125°C, this part covers industrial and automotive under-hood environments. It's happy in a motor-drive enclosure, an outdoor telecom power supply, or an engine-bay ECU. The wide temperature range also means the accuracy spec holds over the full span — no cold-start drift surprises. ## Lifecycle and supply The INA199A3DCKT is an active, current-production part with ROHS3 compliance. No last-time-buy or obsolescence risk on the horizon.","metaTitle":"INA199A3DCKT Current Sense Amplifier, ±1.5% Accuracy","metaDescription":"TI INA199A3DCKT current sense amplifier, ±1.5% accuracy, -0.3V to 26V input, high/low-side sensing, -40°C to 125°C, SC-70-6.
