FEATURES
q COMPLETE UNIPOLAR HIGH-SIDE CURRENT MEASUREMENT CIRCUIT q WIDE SUPPLY AND COMMON-MODE RANGE q INA138: 2.7V to 36V q INA168: 2.7V to 60V q INDEPENDENT SUPPLY AND INPUT COMMON-MODE VOLTAGES q SINGLE RESISTOR GAIN SET q LOW QUIESCENT CURRENT (25µA typ) q SOT23-5 Package DESCRIPTION
Wide input common-mode voltage range, low quiescent current, and tiny SOT-23 packaging enable use in a variety of applications. Input common-mode and power supply voltages are independent and can range from 2.7V to 36V for the INA138 and 2.7V to 60V for the INA168. This current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100. Although designed for current shunt measurement, the circuit invites creative applications in measurement and level shifting. Both the INA138 and INA168 are available in SOT23-5 and are specified for the –40°C to +85°C industrial temperature range. APPLICATIONS
