The 3 µV input offset voltage and 500 pA input bias current allow accurate measurement across low-value shunt resistors (sub-milliohm) without significant voltage error. The 0.3 V/µs slew rate and 45 kHz bandwidth are a deliberate trade-off: fast enough to capture solenoid inrush and load-step events, but filtered enough to reject high-frequency switching noise from adjacent DC-DC converters. This part is specified for the thermal extremes found in engine compartments, transmission control units, and exhaust-aftertreatment electronics. The TSOT-23-8 package (supplier device package TSOT-23-8) keeps the board footprint small, which helps when routing multiple sense channels on a dense ECU layout.","metaTitle":"INA186A1QDDFRQ1 Current Sense Amplifier, AEC-Q100, 45 kHz","metaDescription":"Texas Instruments INA186A1QDDFRQ1 automotive current sense amplifier. 40-V bidirectional, 48 µA supply, 3 µV offset, TSOT-23-8.
