  • RE: INA125: Troubleshooting noise from INA125

    Resolved
    Raymond-- At long last, I've determined the primary source of the -4 to -6 mV/°C amplifier output drift--it was the (#$%&) strain gauges themselves. Despite selecting strain gauges that are CTE matched to the DUT (aluminum), there must be…
