Product details

Package and mounting — what the SC-70-6 means for assembly

The INA199A3DCKR comes in an SC-70-6 package. It is a surface-mount part. The tape-and-reel or cut-tape options let you order production reels or small quantities for prototypes.

Lifecycle and compliance — no obsolescence risk for new builds

There is no end-of-life notice or last-time-buy window to track. For a current-sense amplifier in a SC-70-6 package, this is a straightforward BOM line to qualify — no special handling, no phase-out schedule to manage.

Frequently asked questions

What is the accuracy of INA199A3DCKR?

The INA199A3DCKR has a listed accuracy of ±1.5%. This is the typical accuracy over the full temperature range and input common-mode range, which allows a 1% measurement budget without overspecifying the shunt resistor.

Can INA199A3DCKR sense both high and low side current?

Yes, the INA199A3DCKR supports both high-side and low-side current sensing. The input common-mode range from -0.3 V to 26 V lets you place the shunt on either side of the load.
