Product details

The INA293B3IDBVR: The 10 µV input offset and 1 MHz bandwidth allow accurate sensing across a wide dynamic range, while the 2.7 V to 20 V supply span lets it run off the same rail as the downstream ADC or controller without an extra regulator.

The 1 MHz -3dB bandwidth and 2.5 V/µs slew rate set the usable signal bandwidth for detecting fast current transients.

Package and footprint

The SOT-23-5 package is a standard five-pin footprint shared across many current-sense amplifiers from TI and other vendors. Surface-mount assembly with standard reflow profiles.

Frequently asked questions

What is the equivalent part for INA293B3IDBVR?

The INA4290A2IRGVR is a four-channel current sense amplifier with a 1.1 MHz bandwidth and 2 V/µs slew rate, while the INA254A1IPWAR is a single-channel zero-drift current sense amplifier with 350 kHz bandwidth and 2.4 V/µs slew rate. Neither is a pin-for-pin replacement — the INA4290A2IRGVR has a different package and channel count, and the INA254A1IPWAR has a different package and lower bandwidth. For a single-channel SOT-23-5 current sense amplifier, the INA293B3IDBVR is the direct choice.
