The INA199B1DCKT: Surface-mount assembly with a moisture sensitivity level typical of small-outline plastic packages; the 0.65 mm pitch routes easily on a two-layer board without via-in-pad.
What the ±1.5% accuracy means for your BOM
Zero-drift architecture keeps the offset drift below 1 µV/°C typical, so the error does not walk with ambient temperature in an outdoor or engine-bay enclosure.
High-side and low-side sensing with a 26 V common-mode range
The -0.1 V to 26 V input common-mode range lets the part sit on either side of the shunt — high-side on a 24 V rail with the load referenced to ground, or low-side between the load and ground with the output referred to the system ground. Bandwidth is 80 kHz, adequate for DC current monitoring and low-frequency load transients; switching-frequency ripple above 80 kHz is attenuated by the amplifier's own roll-off.
