TAS6424 / Efficiency@PVDD=14.4V, Load=4Ω

Hi,

The efficiency @PVDD=14.4V, Load=4Ω is better @2MHz than @384kHz according to Fig 33/34 of the datasheet.

However it is better @384kHz than @2MHz according to Fig 16/17 of the datasheet.

Which figure is correct?

Best Regards,

Kuramochi-san,
We are reviewing the graphs and will let you know.

Kuramochi-san,
The team is re-evaluating the datasheet graphs by taking new data.

Hi Gregg-san,

My customer requests to re-measure fig 16/17/33/34 and output power by 120W@4Ω and 200W@2Ω.

Kuramochi-san,
They are being re-measured at this time. They will be updated in the next revision of the datasheet.

Gregg-san,

Could you send me re-measured data antecedently?
When can I receive the data?

Best Regards,

Kuramochi-san,

We are evaluating the 2 ohm tests. When do you need the final data?

Gregg-san,

We need the final data by 1/25(JPT) at the least because they decide the chip of power amp until 1/27(JPT).
