Product details

What this current-sense amp brings to the bench

Its 1.3 MHz bandwidth and 2.5 V/µs slew rate track current changes in a switching regulator's inductor or a brushed DC motor's winding. The supply span runs from 2.7 V up to 20 V.

The 15 µV input offset voltage sets the noise floor on your measurement: across a 1 mΩ shunt, that's a 15 mA offset error before the signal even starts. The 20 µA input bias current adds a small but predictable error term.

Frequently asked questions

What is the bandwidth of INA293A2IDBVT?

The -3 dB bandwidth is 1.3 MHz.

What is the replacement for INA293A2IDBVT?

No direct replacement is listed in the official records. The INA4290A2IRGVR is a four-channel current-sense amp with similar bandwidth (1.1 MHz) and offset (6 µV), but it comes in a different package and is not a pin-for-pin swap. For a single-channel drop-in, stick with the INA293A2IDBVT.
