Product details

Precision three-channel current and voltage monitor

The Texas Instruments INA3221AIRGVR is a three-channel, high-side current and voltage monitor. Its ±0.25% accuracy holds over the full -40°C to 125°C range. The 0V to 26V common-mode input range covers 24V industrial rails with headroom for transients.

Package and mounting — what the 16-VQFN exposed pad means for your board

The 16-VQFN Exposed Pad package measures 4x4 mm and requires a thermal land on the PCB for both heat sinking and electrical ground connection. The exposed pad is the primary thermal path.

Lifecycle and sourcing — active, no end-of-life pressure

TI lists the INA3221AIRGVR as Active with ROHS3 compliance.

Frequently asked questions

Is INA3221AIRGVR compatible with 3.3V logic?

Yes. The INA3221 operates from a 2.7V to 5.5V supply and its I2C interface is 3.3V-logic compatible. The bus voltage sense inputs accept 0V to 26V independent of the logic supply.
