The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and desired noise rejection. A larger capacitor value can provide better noise rejection, but may also increase the startup time.
Yes, the LM385BYM-2.5/NOPB can be used as a voltage reference for an ADC. Its low noise and high stability make it suitable for this application. However, ensure that the ADC's input voltage range is compatible with the LM385BYM-2.5/NOPB's output voltage.
To ensure stability, follow the recommended PCB layout guidelines, use a low-ESR output capacitor, and avoid long output traces. Also, ensure that the input voltage is within the recommended range and that the device is not subjected to high temperatures or voltage transients.
The LM385BYM-2.5/NOPB is rated for operation up to 125°C. However, its accuracy and stability may degrade at high temperatures. If your application requires operation above 125°C, consider using a more temperature-stable voltage reference or taking additional measures to ensure the device's reliability.
The output impedance of the LM385BYM-2.5/NOPB can be calculated using the equation: Zout = (ΔVout / ΔIout) || R_out, where ΔVout is the change in output voltage, ΔIout is the change in output current, and R_out is the output resistance. The output impedance is typically around 10-20 ohms.
