Product details

What this current-sense amplifier brings to the rail

The INA2290A1IDGKR: Its 6 µV input offset keeps the error low when you are reading millivolt drops across a sense resistor, and the 1.1 MHz gain-bandwidth product gives enough bandwidth for switching-frequency ripple or load-transient capture. Supply current sits at 680 µA, which is modest for a precision sense amp — it will not eat a noticeable slice of the standby budget in a battery-powered controller.

The wide temperature grade also covers industrial PLC racks that sit in unventilated enclosures next to power stages.

Frequently asked questions

Is INA2290A1IDGKR RoHS compliant?

Yes, it is ROHS3 compliant. No conflict with EU RoHS requirements for lead-free assembly.

What is the replacement for INA2290A1IDGKR if it is not available?

The INA4290A2IRGVR is a quad-channel current-sense amplifier with similar bandwidth and offset, but it is not pin-compatible and has a different number of circuits. For a drop-in substitute, verify pinout and gain with the manufacturer.
