Current sense amplifier for precision shunt monitoring
Supply range and quiescent draw
The INA2290A4IDGKR operates from a single supply spanning 2.7 V to 20 V, covering common 3.3 V, 5 V, and 12 V rails without an extra regulator. Quiescent supply current is 680 µA, low enough for always-on current monitoring in battery-backed systems where every milliamp matters.
Housed in an 8-VSSOP (also listed as 8-TSSOP / 8-MSOP with 0.118" body width), this is a surface-mount part.
ROHS3 compliance is confirmed, making it suitable for markets with current RoHS restrictions.
