    Thread Summary
    
                The user is inquiring about the start-up time for the ADR4525BRZ voltage reference when used with the DAC AD3552R. The support engineer suggests it should be a few tens of microseconds, similar to the ADR444. The input capacitors are 0.1uF and 1uF, and the output capacitors are two 1uF and one 0.1uF.

    Hi Team,
    

    I'm planning to use ADR4525BRZ as 2.5V voltage reference for the DAC AD3552R
    

    What is the start-up  time for the IC as i couldn't get those details in datasheet.
    

    The Cin capacitors provided are 0.1uF and 1uF
    

    The Cout capacitors provided are two 1uF and one 0.1uF
    

    

    Regards,
    

    Abhishek
