    Design Notes

    • Check the input common-mode range against the actual signal, especially in single-supply rails where ground-referenced signals sit at the edge.
    • Capacitive load drives stability; add series isolation when driving cables or ADC inputs directly.
    • Offset voltage and its drift, not gain bandwidth, usually set the achievable accuracy in DC instrumentation.
    • Decouple at the pin with the smallest package capacitor that meets the transient requirement, returned to a local ground.
