Product details

Current-sense amp for 2.7–20 V rails

The Texas Instruments INA293A5IDBVT is a single-channel current-sense amplifier in a SOT-23-5 package. It monitors current by amplifying the voltage across a shunt resistor, outputting a ground-referenced signal proportional to the load current. The supply span from 2.7 V to 20 V covers common logic and industrial bus voltages.

Active lifecycle — no LTB risk for new BOMs

For a BOM freeze or a new design, this part is a stable choice — no PCN-driven respin required in the near term.

Frequently asked questions

Is INA293A5IDBVT RoHS compliant?

Yes, the INA293A5IDBVT is ROHS3 compliant.

Does INA293A5IDBVT require an external resistor?

Yes, like all current-sense amplifiers, the INA293A5IDBVT requires an external shunt resistor placed in the current path. The amplifier measures the voltage drop across that shunt and outputs a ground-referenced voltage proportional to the current.

What is the INA293A5IDBVT equivalent?

The INA254A1IPWAR is a zero-drift current-sense amplifier in the same family with a 350 kHz bandwidth and 2.4 V/µs slew rate — a functional alternative if lower bandwidth is acceptable. The INA4290A2IRGVR is a quad-channel current-sense amp with 1.1 MHz bandwidth and 2 V/µs slew rate, useful when multiple channels are needed on the same package.
