TAS5825M: Please help check the schematic design of the TAS5825M.

pan long

Part Number: TAS5825M

Tool/software:

1. Is it sufficient to use a 10uF capacitor to ground when the actual power consumption of the speaker is 10W on one side at PVDD=20V for the TAS5825M chip?

2. Is there any hidden danger in using 10uH + 0.68uF LC filter combination for the speaker?

Hi Pan Long,

Answers:

1 usually you can use 22uF to get better THD.

2 the LC filter should meet the cutoff frequency requirement. you can refer to the LC design guide below:https://www.ti.com.cn/cn/lit/an/slaa701a/slaa701a.pdf

Br,

Do you have any suggestions on the heat dissipation of our amplifier circuits, do we need to add more heat dissipation?

TI has not special recommendation for heat sink.

also, only 10w output, usually it even doesn't need the heat sink sometimes for this thermal pad down device.
