INA180
Overview
The INA180, INA2180, and INA4180 (INAx180) current sense amplifiers are designed for costoptimized applications. These devices are part of a family of current-sense amplifiers (also called currentshunt 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.
- 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)
