ADS8900B: Capacitor selection

Part Number: ADS8900B

Hi Team,
The datasheet of ADS8900B suggests using a 1uF, X7R grade capacitor with a 10V rating at its DACAP pin
What change does it use a X7R grade 16V rating capacitor instead of 10V?
Also, how the case style of the capacitor affects the performance?.

    Hello Shibin,

    There is no issue using a higher voltage rated capacitor such as a 16V or 25V rated part.  It is important to use a ceramic capacitor that meets the desired temperature range (X7R, -55C to 125C) with low ESR.  SMT package should be used for best performance and smallest size.  Standard 0402, 0603 or 0805 will work well.

    Hello Keith,
    Thank you for your reply.

    I've read an article related to this.
    This article says larger the case style is lesser will be the change in capacitance.
