Part Number: TAS5825M


Hello I followed the design guide line in the datasheet of TAS5825M It just hard to get 22uf JB ceramic Capacitor (C3 and C6 in the schematic for the stereo configuration  ) , any suggestion for alternative ?

it also not recommend for new design and rare to find 

thank you

    Dear Customer,

    Do you mean the decoupling cap for PVDD?
    Please refer to page 79 of the datasheet, it requires that: the power supply input must be decoupled with some
    good quality, low ESL, Low ESR capacitors larger than 22 μF.

    Hence, you can choose your decoupling cap with the standard above.

    Regards,
    Alix Wan.

    >100uF electrolytic low ESR capacitor like the Panasonic FM or FR series is also possible. For high power you can go bigger (470-820uF) for better bulk decoupling.

    For high frequency decoupling you still need 100n small SMD capacitor on each side.
