High-side current sense with ±0.01% accuracy
The INA216A1RSWR: This accuracy level means the part resolves current changes down to 100 ppm of the full-scale shunt voltage — critical for precision battery monitoring, power-rail diagnostics, or closed-loop current control where a 1% sense resistor tolerance would dominate the error budget.
Zero-drift topology and temperature range
The Zero-Drift architecture continuously nulls the input offset voltage, keeping the measurement stable from -40°C to 125°C without the warm-up drift typical of conventional amplifiers.
Package footprint and board integration
Housed in a 10-UFQFN package (supplier package 10-UQFN, 1.8 mm x 1.4 mm body), the part occupies roughly the area of a 0603 resistor — the limiting factor for board space is the shunt resistor and its Kelvin-sense traces, not the monitor itself.
The date-code trace on incoming stock is verified against TI's factory marking standards before shipment.
