TAS5825M: TAS5825 efficiency BD modulation and 1SPW modulation

Kevin Huang8

Part Number: TAS5825M
Other Parts Discussed in Thread: TAS5805M, TAS5805

Please provide TAS5825M 1SPW modulation efficiency waveform,cause customer need comparison TAS5825M BD modulation and 1SPW modulation efficiency,
For TAS5805M example, the TAS5805M efficiency table BD modulation and 1SPW modulation.

Customer is currently evaluating the efficiency data of TAS5805 and TAS5825, so such information is needed.

Hi Kevin,

Normally our datasheet couldn't cover all conditions performance data. It's suggested to measure required data with our EVM board.

BTW, could you share us customer application condition? Such as PVDD voltage / Speaker load / BTL or PBTL / LC filter configuration... We could help to check whether there is available data in our hand.

Regards

Datasheet highlight 1PW modulation achieve higher efficiency, Customer need to know the efficiency performance of TAS5805 1PW modulation worse than BD modulation efficiency? Is Difference Figure31. and Figure51.

Hi,

TAS5805M 1SPW / BD mode efficiency data has something wrong. Our team is working on the update.

Below figure shows 12V PVDD, 768kHz PWM, 8ohm load, 1SPW and BD modulation efficiency comparison.

Hi Kevin,

We are still working on it, no solid timeline yet. During this time, you can ask for the data you need here. We will check if we have covered your condition in our database. Thanks!

Regards,

Sam
