It measures current across a shunt resistor on high-side or low-side rails, outputting a rail-to-rail voltage proportional to the sensed current. The zero-drift architecture holds input offset voltage to 3 µV, which keeps measurement error low across the -40°C to 125°C temperature range — important for precision monitoring in motor drives, battery management, and power-supply feedback loops. ## Power budget and bandwidth — what the 48 µA and 45 kHz tell you At 48 µA quiescent supply current, this part fits always-on current-sense nodes in battery-powered equipment where every microamp matters. The 45 kHz gain-bandwidth product is sufficient for DC and low-frequency load transients — think battery charging profiles, overcurrent detection, or average current monitoring — but not for high-speed switching regulator loops that need MHz bandwidth. The 0.3 V/µs slew rate matches the 45 kHz GBW; expect clean settling on step changes from the shunt. ## Package and mounting Housed in a TSOT-23-8 (SOT-23-8) surface-mount package. The small footprint suits dense PCB layouts in handheld or embedded designs. Tape & Reel and Cut Tape options available for prototyping or production runs.","metaTitle":"TI INA186A3IDDFR Current Sense Amplifier, Zero-Drift","metaDescription":"TI INA186A3IDDFR zero-drift current sense amplifier. 48 µA supply, 3 µV offset, 1.7-5.5 V supply, -40 to 125°C.
