INA4180A4IPWR

Texas Instruments' INA180, INA2180, and INA4180A4IPWR (INAx180) current sense amplifiers are designed for cost-optimized applications. These devices are part of a family of 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 INAx180 integrate 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.All these devices operate from a single 2.7 V to 5.5 V power supply. The single-channel INA180 draws a maximum supply current of 260 µA; whereas, the dual-channel INA2180 draws a maximum supply current of 500 µA, and the quad-channel draws a maximum supply current of 900 µA.The INA180 is available in a 5-pin, SOT-23 package with two different pin configurations. The INA2180 is available in an 8-pin VSSOP package. The INA4180A4IPWR is available in a 14-pin TSSOP package. All device options are specified over the extended operating temperature range of -40°C to +125°C.<strong>Features:</strong> Common-mode range (VCM): -0.2 V to +26 V, High-bandwidth: 350 kHz (A1 devices), Offset voltage: ±150 µV (max.) at VCM = 0 V, ±500 µV (max.) at VCM = 12 V, Accuracy: ±1% gain error (max.), 1 µV/°C offset drift (max.), Gain options: 20 V/V (A1 devices), 50 V/V (A2 devices), 100 V/V (A3 devices), 200 V/V (A4 devices), Quiescent current: 260 µA max.
