Overview
The INA4180A3IPWR is a quad-channel, high-accuracy current-sense amplifier produced by Texas Instruments. This device is part of the INAx180 family, designed for cost-optimized applications in current sensing. It can accurately measure voltages developed across current-sense resistors at common-mode voltages ranging from –0.2 V to +26 V, independent of the supply voltage. The INA4180A3IPWR operates from a single 2.7-V to 5.5-V power supply and is available in a 14-pin TSSOP package.
