Introduction

AI Translation

The INA181, INA2181, and INA4181 (INAx181) current-sense amplifiers are designed for cost-optimized solutions. These devices are a series of bidirectional current-sense amplifiers (also known as current shunt monitors) that can sense the voltage drop across a current-sense resistor at common-mode voltages ranging from -0.2V to +26V, independent of the supply voltage. The INAx181 series integrates a matched resistor gain network with four fixed-gain device options: 20V/V, 50V/V, 100V/V, or 200V/V. This matched gain resistor network minimizes gain error and reduces temperature drift. These devices are powered by a single 2.7V to 5.5V supply. The single-channel INA181 consumes a maximum supply current of 260μA; the dual-channel INA2181 consumes a maximum supply current of 500μA, and the quad-channel INA4181 consumes a maximum supply current of 900μA. The INA181 is available in a 6-pin SOT - 23 package. The INA2181 is available in a 10-pin VSSOP package. The INA4181 is available in a 20-pin TSSOP package. All device options are specified for an extended operating temperature range of -40°C to +125°C.
