TS12A12511: Do you have any data about ACPSRR of TS12A12511?

Other Parts Discussed in Thread: TMUX6219

Hello guys,

One of my customers is considering using TS12A12511 for their new products.

At this moment, they have the following question. Could you please give me your reply for them?

Q. Do you have any data about ACPSRR(AC Power Supply Rejection Ratio) of TS12A12511?

     If you have a graph like Figure 6-28 ( ACPSRR vs Frequency graph) on page 18 of  TMUX6219 datasheet,

     it is the best for me.

     TMUX6219 datasheet

Your reply would be much appreciated.

Best regards,

Kazuya.

    Hey Kazuya,

    We do not have data on the ACPSRR of the TS12A12511. However, a de-coupling capacitor on the supply line is the best method for reducing the noise. This will decouple any AC noise down to ground. The datasheet recommends a 0.1uF capacitor. 
    I'd also recommend reducing the trace distance between this capacitor and the supply. This will help minimize any extra resistance and inductance that may accumulate through the trace. 

    Thanks,
    Rami
