INA290A3QDCKRQ1 TI Current Regulation/Management

The INA290A3QDCKRQ1 is an automotive-grade (AEC-Q100) precision current-sense amplifier from Texas Instruments, featuring a fixed gain of 100 V/V. It is designed for DC current measurement and high-speed applications like overcurrent protection, offering a bandwidth of 1.1 MHz. The device provides ultra-low offset voltage of ±20 µV (max), low gain error of 0.15% (max), and high DC CMRR of 160 dB for exceptional accuracy. It operates over a wide common-mode range of 2.7V to +120V and a supply range of 2.7V to 20V. Housed in a 5-pin SC-70 (DCK) package, it operates over -40°C to 125°C. Applications include automotive motor drives, battery management systems (BMS), power steering, and industrial automation requiring AEC-Q100 qualification.
