Description
General part information
INA2181-Q1 Series
The INA181-Q1, INA2181-Q1, and INA4181-Q1 (INAx181-Q1) 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 –0.2V to 26V, independent of the supply voltage. The INAx181-Q1 family integrates a matched resistor gain network in four, fixed-gain device options: 20V/V, 50V/V, 100V/V, or 200V/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-Q1 draws a maximum supply current of 260µA; whereas, the dual-channel INA2181-Q1 draws a maximum supply current of 500µA, and the quad-channel INA4181-Q1 draws a maximum supply current of 900µA.
The INA181-Q1 is available in both the 6-pin, SOT-23 and SC70 packages. The INA2181-Q1 is available in a 10-pin, VSSOP package. The INA4181-Q1 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.
