For a 100 kHz switching supply, the closed-loop gain stays flat within a fraction of a dB — the phase shift at those frequencies is low enough to keep the current-loop response predictable. If your application runs above 300 kHz switching, budget for the bandwidth limit when sizing the sense resistor and the feedback network. The SOT-23-5 package is surface mount.","metaTitle":"INA293B4QDBVRQ1 Current Sense Amplifier, AEC-Q100, 900 kHz","metaDescription":"TI INA293B4QDBVRQ1 automotive current sense amplifier in SOT-23-5. 900 kHz bandwidth, 5 µV offset, 2.7V–20V supply.

The supply voltage range of 2.7 V to 20 V covers typical automotive battery rails (12 V, 24 V). The 5 µV input offset allows accurate measurement with small shunt drops, minimizing power loss in the sense resistor."},{"question":"What is the difference between INA293B4QDBVRQ1 and INA293B3QDBVRQ1?","answer":"The difference is in the gain version. The '' suffix denotes a specific gain setting within the INA293 family. Both share the same SOT-23-5 package, AEC-Q100 qualification, and supply range.
