🔧 Application Guidelines
Design Considerations
The AD586 is a high accuracy, low noise voltage reference that requires careful consideration of the PCB layout, power supply, and load conditions to ensure optimal performance. The device should be connected to a low impedance power supply, and the output should be decoupled with a capacitor to reduce noise.
Installation Guidelines
The AD586 is available in an 8-lead MSOP package and an 8-lead SOIC package. The device should be handled with care to avoid damage to the leads or the package. The PCB should be designed to provide a low thermal resistance path to the device to ensure reliable operation.
Operational Notes
The AD586 is a sensitive device that requires careful handling and operation. The device should not be exposed to high temperatures, high humidity, or high vibration. The output of the device should not be shorted to ground or to any other voltage source.
