TAS5805M: THD manager, level meter, DC blocking, Thermal foldback

Part Number: TAS5805M
Other Parts Discussed in Thread: TAS5805

Hi Sir,

I saw the TAS5805M spec mentions THD manager, level meter, DC blocking,

But it doesn't discript more about them.

I  would like to know what they mean and if it is necessary for us to use it.

Could you help this?

  • Hi Mimon

     Level meter is some registers, that you could use their value to calculate what is current output. Seldom been used.

     DC blocking is a internal digital filter, to remove DC signal which may damage Speaker. Default enabled, no need to adjust.

     THD manager, I'm not sure which block we are talking about, may I know where do you find this one?

  • Hi Sir

    Please refer the following picture as TAS5805 spec.

    I marked blue color for the THD manager.

    Regarding Level meter, where are those register and what's the formula if I get the register value to transform the current output?

    (is it the output voltage or current?)

  • Hi Simon

      It seems describes the Mono 1.1 process flow, the Woofer path. And is talking about Clipper & Makeup Gain. Also not been sued often.
