7.1 Application Information

The INAx126 measures small differential voltage with high common-mode voltage developed between the noninverting and inverting input. The high input impedance make the INAx126 an excellent choice for a wide range of applications. The INAx126 can adjust the functionality of the output signals by setting the reference pin, giving additional flexibility that is practical for multiple configurations.
