TAS5760L: Soft Clipper behavior

Hikaru Nozaki

Part Number: TAS5760L

Dear Team,

I have a question about Soft Clipper of TAS5760L.
Is the behavior of set "Resistor to GVDD" to (Open), same as set "Resistor to GVDD" to 0Ω?
I'd like to ask wheather I can disactivate the use of Soft Clipper or not.

Best Regards,

Nozaki

I think you may think there's only one resistor at SFT_CLIP pin and asked this question. But actually there are two resistors you need to set them both correctly.

According to below table:

Dear He

I think R_CLIP2 is "Resistor to GND", R_CLIP1 is "Resistor to GVDD". Is this right?
If so, what i'd like to know is that Output Voltage when R_CLIP1 is became (open).
Even in that case, Output voltage is 10.33V?

That's no problem.

In this situation, there would be no voltage supplied into SFT_CLIP pin, I'm afraid there would be almost no output at all.

Dear He

I understood. Thank you for your answer.
I have anther question. According to TAS5760L's datasheet, Output Voltage is 10.33[Vrms] in the below situation.
PVDD : 12[V]
Resistor to GND : (open)
Resistor to GVDD : 0
In this case, isn't ”Output Voltage[Vrms]” mistaken for "Output Voltage[Vpk]"?

Can TAS5760L output about 14.6[Vpk] which higher than PVDD 12[V]?

This won't happen.

In that table, it's more like 10%THD output power. Or like you said, also similar with unclipped peak value.
