Product details

Current sense amplifier with 3 µV offset and wide supply range

Its 2 V/µs slew rate supports fast overcurrent detection in motor drives, solenoid control, and power-management loops. The 2.7 V to 20 V supply span lets it run off common rails from 3.3 V logic supplies up to 24 V industrial buses without an extra regulator.

What the 3 µV offset and 680 µA supply mean for your BOM

A 3 µV input offset lets the INA2290A2IDGKR resolve tens of milliamps through a 1 mΩ shunt, which keeps shunt power dissipation low and board area small. The 680 µA supply current is low enough for always-on current monitoring in battery-powered equipment — a 24/7 IoT node drawing 680 µA from the sense amplifier alone is acceptable in a system with a 500 mAh battery.

Package and mounting: 8-VSSOP with Tape & Reel options

MSL level should be verified from the latest TI packaging data.

ROHS3 compliance is confirmed, so it meets EU and global material restrictions without exemption tracking.

Frequently asked questions

What are the alternatives or equivalents to INA2290A2IDGKR?

The closest functional alternative within the same family is the INA4290A2IRGVR, a quad-channel version of the same current sense amplifier core. For a single-channel zero-drift alternative, the INA254A1IPWAR offers 350 kHz bandwidth and 2.4 V/µs slew rate. Neither is a direct pin-for-pin replacement; verify the package and number of channels against your layout.
