Package and board-fit for the 10-UQFN footprint
The INA199A2RSWR comes in a 10-UFQFN package with a supplier device package size of 10-UQFN (1.8x1.4) — the 0.50 mm pitch and small body demand a solder-paste stencil aperture sized for the exposed pad to avoid tombstoning during reflow.
What the ±1.5% accuracy and 14 kHz bandwidth mean on the bench
With a 14 kHz bandwidth, the INA199A2RSWR filters out switching noise above that frequency — useful for sensing DC current in a motor drive or power supply output where the ripple frequency is below 14 kHz, but it will alias PWM edges above that unless you add an external RC filter ahead of the input pins.
High-side and low-side sensing with a -0.3V to 26V common-mode range
The input voltage range of -0.3V to 26V allows this current sense amplifier to sit on either the high side (between the supply rail and the load) or the low side (between the load and ground) — the -0.3V negative limit means it can tolerate a brief ground bounce below the negative rail without latching up.
No pin-compatible second-source is listed as an official cross-reference, but the automotive-grade INA199B2QDCKRQ1 shares the same ±1.5% accuracy and sensing method if the design requires AEC-Q100 qualification.
