Three fixed gains are available: 50 V/V, 100 V/V, and 200 V/V. The low offset of the – ±1.5% Gain Error (Maximum Over zero-drift architecture enables current sensing with Temperature) maximum drops across the shunt as low as 10-mV – 0.5- μV/°C Offset Drift (Maximum) full-scale. – 10-ppm/°C Gain Drift (Maximum) These devices operate from a single 2.7-V to 26-V • Choice of Gains: power supply, drawing a maximum of 100 μA of supply current. All versions are specified from –40°C – INA199x1: 50 V/V to 105°C, and offered in both SC70-6 and thin UQFN- – INA199x2: 100 V/V 10 packages. – INA199x3: 200 V/V • Quiescent Current: 100 μA (Maximum) Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) • Packages: SC70, UQFN-10 SC70 (6) 2.00 mm × 1.25 mm INA199 2 Applications UQFN (10) 1.80 mm × 1.40 mm • Notebook Computers (1) For all available packages, see the orderable addendum at the end of the data sheet. • Cell Phones • Qi-Compliant Wireless Charging Transmitters • Telecom Equipment • Power Management • Battery Chargers • Welding Equipment Simplified Schematic 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
