Hi team,

Is there Power dissipation vs Output power plot at 8R speaker for TAS5431-Q1?

If TAS5431-Q1 data is not available, TAS5411-Q1 data should be fine.

Tsuji-san,

8ohm efficiency data is not available. Which specific output power level you are interested in? we can collect more data based on EVM.

Hi Dylan,

Thank you.

Could you measure 3W @8ohm?

Tsuji-san,

The system efficiency at 3W'8Ohm is around 78%.

This data is based on TAS5411Q1EVM.

Hi Frank,

Could you measure the efficiency at 1W and 2W, too?

Tsuji-san,

It is 67% @1W,75% @2W.

Please note the data is base on EVM board, there is LDO and other elements may influence the efficiency. This is the system efficiency.

Best,

Frank
