For a 0.01 Ω sense resistor on a 2.7V supply, the LSB works out to roughly 8 µA per count, which is fine-grained enough to track a smartphone's sleep current or a IoT sensor's deep-sleep draw. The 2.7V to 5.5V input range covers single-cell Li-ion (3.0-4.2V), two-cell alkaline (3.0V), and regulated 3.3V or 5V rails — no external LDO needed if the battery voltage stays within this window. ## Package and board-fit note Housed in the 8-uMAX/uSOP package (3.00 mm body width, 0.118-inch pitch), the DS2740U+T&R shares the same land pattern as the standard 8-MSOP. The supplier device package is 8-uMAX/uSOP — the footprint is a 0.65 mm pitch, 1.1 mm max seated height.","metaTitle":"DS2740U+T&R 15-Bit Current Gauge, 2.7V-5.5V, 8-uMAX","metaDescription":"Analog Devices DS2740U+T&R 15-bit current gauge, 2.7V to 5.5V input, 8-uMAX/uSOP.
