TAS6424E-Q1: EMI and Effeciency

Part Number: TAS6424E-Q1
Other Parts Discussed in Thread: TAS6424-Q1, TAS6424E

Hello,

Our customer plans to utilize TAS6424E-Q1 for next project. Here are some questions which is not on the datasheet.

#1  What is difference of EMI level between TAS6424-Q1 and TAS6424E-Q1 on the EVM?

#2  On TAS6424E datasheet, Figure 7-6, 7-7 and 7-8 are 14.4V power supply condition.

But our customer wants to see same characteristic graph at 25V supply.

              Figure 7-6. Efficiency vs Output Power - 14.4 V - 4 Ω

              Figure 7-7. Efficiency vs Output Power - 14.4 V - 4 Ω (Zoomed)

              Figure 7-8. Power Dissipation vs Output Power - 14.4 V - 4 Ω

Regards,

Mochizuki
