TAS2564: can the tas2564 amp support 4 ohm ,8 watt speaker or more Watt??

Hello Gary,

Thank you for reaching out. From our portfolio, Output power of 8W can be achieved more easily using an external PVDD than from internal boost. TAS2564 was tested to have 6.4 Ohm minimum. However, there are other amps that supports 4 ohms from the portfolio. A potential candidate can be TAS2563/62 which supports 4 ohm load and outputs above 8 watt when it is in boost bypass mode, but that requires an external PVDD.

Dear Luis:

Thank you for your reply.

I need  boost function in a AMP chip.

My customer  spec define need  8W

Assuming I use 6.4 ohm speakers, can I meet 8 watt THD+N =0.1% or 1%?

Can we adventurous do it ?

Hi, Gary,

We cannot guarantee that it will reach the 8W at THD+N= 0.1% or 1%. But based on the electrical characteristics, I would say that the device should reach more than 7W with a lower load (in the plots, an 8ohms load can reach ~7.2W under these THD+N levels).

In case the customer is interested in this device, I strongly recommend to use a VBAT=5.5V.
