Overview
The INA4180A3QPWRQ1 is a quad-channel, automotive-grade current-sense amplifier produced by Texas Instruments. This device is part of the INAx180-Q1 family, designed for cost-optimized applications in both low-side and high-side configurations. It operates within a common-mode voltage range of –0.2 V to +26 V, independent of the supply voltage, which ranges from 2.7 V to 5.5 V. The INA4180A3QPWRQ1 integrates a matched resistor gain network, providing a fixed gain of 100 V/V, which minimizes gain error and reduces temperature drift.
