No pin-compatible second-source is listed as an official cross-reference, but the automotive-grade INA199B2QDCKRQ1 shares the same ±1.5% accuracy and sensing method if the design requires AEC-Q100 qualification.","metaTitle":"Texas Instruments INA199A2RSWR Current Sense, ±1.5% Accuracy","metaDescription":"INA199A2RSWR current sense amplifier from TI, ±1.5% accuracy, high/low-side sensing, -0.3V to 26V input, 10-UQFN.
