Product details

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.

Frequently asked questions

What is the bandwidth of INA2290A4IDGKR?

The gain-bandwidth product is 850 kHz, and the slew rate is 2 V/µs, which together define the small-signal bandwidth for measuring fast current transients.

Is INA2290A4IDGKR RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest RoHS exemption limits.

What is the closest functional equivalent to INA2290A4IDGKR?

The INA4290A2IRGVR is a four-channel current sense amplifier in the same family, with similar 2 V/µs slew rate and 2.7 V minimum supply, but with 6 µV offset and 1.3 mA supply current per channel. It is a drop-in for multi-channel designs, not a pin-compatible single-channel replacement.
