PRODUCTION DATA. INA180, INA2180, INA4180 SBOS741G – APRIL 2017 – REVISED APRIL 2020 INAx180 Low- and High-Side Voltage Output, Current-Sense Amplifiers 1 1 Features 1 • Common-mode range (VCM): –0.2 V to +26 V • High bandwidth: 350 kHz (A1 devices) • Offset voltage: – ±150 µV (maximum) at VCM = 0 V – ±500 µV (maximum) at VCM = 12 V • Output slew rate: 2 V/µs • Accuracy: – ±1% gain error (maximum) – 1-µV/°C offset drift (maximum) • 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 maximum (INA180) 2 Applications • Motor control • Battery monitoring • Power management • Lighting control • Overcurrent detection • Solar inverters 3 Description The INA180, INA2180, and INA4180 (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 8-pin, VSSOP and WSON packages. The INA4180 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.
