Product details

Current sense amplifier for precision shunt monitoring

A 1 MHz bandwidth and 2.5 V/µs slew rate support DC motor current loops, power-supply monitoring, and overcurrent detection. The 10 µV input offset voltage allows accurate measurement of shunt drops as low as a few millivolts without calibration. The SOT-23-5 package suits space-constrained boards.

The 2.7 V minimum supply lets it run from a 3.3 V rail with headroom; the 20 V maximum covers 12 V and 24 V systems with margin for load-dump transients.

It is ROHS3 compliant.

Frequently asked questions

Is INA293A3IDBVR RoHS compliant?

Yes, the INA293A3IDBVR is ROHS3 compliant.

What is the bandwidth of INA293A3IDBVR?

The -3 dB bandwidth is 1 MHz.

When sourcing INA293A3IDBVR, what's the closest functional second-source?

It is not a pin-compatible drop-in; the INA293A3IDBVR is single-channel in SOT-23-5, while the INA4290A2IRGVR is a four-channel device in a different package. For a single-channel alternative, the INA254A1IPWAR offers zero-drift architecture with 350 kHz bandwidth and 2.4 V/µs slew rate, also in a different package.
