Precision current sense with a 100 V supply ceiling
It operates from a 5 V to 100 V supply span, making it suitable for monitoring rails from low-voltage logic supplies up to 48 V telecom or 72 V industrial buses. The 200 kHz gain-bandwidth product supports moderate-speed current monitoring for overcurrent detection, load monitoring, and closed-loop control loops in power supplies and motor drives.
The 3 µV input offset voltage is the headline accuracy spec. For a 10 mΩ shunt carrying 1 A, the sense voltage is 10 mV — the offset contributes 0.03% error at that point, which keeps the measurement within a tight tolerance without post-calibration. The 420 µA supply current is modest for a precision amplifier, so it can be left powered continuously on a 24 V rail without a significant quiescent penalty. The 60 pA input bias current means the shunt resistor value can be pushed into the low-ohm range without offset drift from bias current flowing through the sense element.
It is not rated for automotive under-hood environments, outdoor telecom cabinets, or industrial enclosures that see freeze-thaw cycles. For extended temperature applications, a part like the AD8417WHRZ (automotive grade, -40°C to 150°C) would be the cross-shop candidate, though it carries a different package and pinout.
8-MSOP package and surface-mount assembly
The supplier device package is 8-MSOP, and the broader package / case is listed as 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). The part ships in Tube form, which is typical for low-volume prototyping and small-batch production. For reflow, standard MSOP profiles apply — no exposed pad, so thermal dissipation is through the leads only.
