Bi-Directional – 350kHz Current Sense Amplifier – 26V

Description INA181A4IDBVT -Bi-Directional – 350kHz Current Sense Amplifier – 26 datasheet Description of the INA181 The INA181, INA2181, and INA4181 (INAx181) current sense amplifiers are designed for cost-optimized applications. These devices are part of a family of bidirectional, current-sense amplifiers (also called current-shunt monitors) that sense voltage drops across current-sense resistors at common-mode voltages from –0.2 V to 26 V, independent of the supply voltage. The INAx181 family integrates a matched resistor gain network in four, fixed-gain device options: 20 V/V, 50 V/V, 100 V/V, or 200 V/V. This matched gain resistor network minimizes gain error and reduces the temperature drift. These devices operate from a single 2.7-V to 5.5-V power supply. The single-channel INA181 draws a maximum supply current of 260 µA; whereas, the dual-channel INA2181 draws a maximum supply current of 500 µA, and the quad-channel INA4181 draws a maximum supply current of 900 µA. The INA181 is available in a 6-pin, SOT-23 package. The INA2181 is available in 10-pin, VSSOP, and WSON packages. The INA4181 is available in a 20-pin, TSSOP package. All device options are specified over the extended operating temperature range of –40°C to 125°C. Packing List: 1 x INA181A4IDBVT -Bi-Directional – 350kHz Current Sense Amplifier – 26
