High-side current sense with ±0.03% accuracy — what that means for your rail
The Texas Instruments INA216A4RSWT is a Zero-Drift series high-side current shunt monitor that measures current by sensing the voltage drop across an internal, integrated sense resistor. Its accuracy is ±0.03%.
Package and footprint — 10-UQFN (1.8 x 1.4 mm)
The INA216A4RSWT comes in a 10-pin UFQFN package (supplier device package 10-UQFN, 1.8 x 1.4 mm body).
No external sense resistor — integrated shunt simplifies the BOM
Because the INA216A4RSWT uses an internal sense resistor, you do not need to add an external shunt resistor.
Lifecycle and compliance — active, ROHS3, no obsolescence concern
The INA216A4RSWT is listed as Active on TI's product status, with ROHS3 compliance. For a BOM freeze or a long-life design, this part carries no near-term supply risk from obsolescence.
