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.","metaTitle":"INA3221AIRGVR Current/Voltage Monitor, ±0.25% Accuracy","metaDescription":"TI INA3221AIRGVR high-side current/voltage monitor with ±0.25% accuracy, 0V to 26V input, -40°C to 125°C.
