Typical Application Circuit

Applications

• Hot Swap
• Storage Drives

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.
