The INA216A4RSWR comes in a 10-UQFN package measuring 1.8 mm x 1.4 mm (supplier device package 10-UQFN). Surface-mount only; no through-hole option.
ROHS3 compliant. The product status is Active.
The INA216A4RSWR is a high-side current monitor with ±0.03% accuracy. It measures current on the supply rail above the load, which is the preferred method for detecting short circuits and for loads that share a common ground.
The INA199B2QDCKRQ1 is an automotive-grade (AEC-Q100) Zero-Drift current sense amplifier that supports both high-side and low-side sensing, but its accuracy is 1.5% — significantly looser than the INA216A4RSWR's ±0.03%. The INA199 also operates from a 0.1V input range, which is much narrower. For a precision monitor where ±0.03% matters, the INA216A4RSWR is the tighter part; the INA199 is a lower-accuracy alternative for automotive-qualified applications.
