Product details

Zero-Drift current sense amp for precision rail monitoring

The INA213BIRSWT measures current through a shunt resistor on supply rails from 2.7 V up to 26 V.

The 5 µV input offset voltage and 28 µA input bias current are specified in the datasheet. The 14 kHz gain-bandwidth product limits the part to DC and low-frequency ripple sensing.

Supply range 2.7 V to 26 V — one part for multiple rail voltages

The INA213BIRSWT operates from a single supply spanning 2.7 V to 26 V. The common-mode input range extends from the negative rail up to 26 V.

The 10-UFQFN package with a 1.8 mm x 1.4 mm footprint is a tiny land-grid array — surface-mount only, no leads to inspect. It demands a well-planned PCB layout: keep the shunt traces short and Kelvin-connected to the sense amplifier inputs to avoid IR drops that would swamp the 5 µV offset.

The part is ROHS3 compliant. For new designs, there is no lifecycle risk; for existing BOMs, it remains a safe long-term choice.

Frequently asked questions

Is INA213BIRSWT a Zero-Drift amplifier?

Yes, the INA213BIRSWT is part of TI's Zero-Drift series, which uses chopper-stabilization to achieve the 5 µV input offset voltage and low drift over temperature.

Can I use INA213BIRSWT for low-side current sensing?

Yes. The common-mode input range includes the negative rail, so the INA213BIRSWT works for low-side sensing where the shunt is between the load and ground. It also handles high-side sensing up to 26 V.
