Dear TI

Please find the attached schematic for your review .

I have some doubts

In datasheet 8 Ohms load we need to connect 22uH inductor . Pls suggest me how to select inductor this application

When this device is active mode what is the peak current ,Input voltage 12V/ 8Ohms load Stero mode

We are unable to find out EVM kit for this specific device .

Regard

Hi Nagaraj,

I'm a bit confused. The link you gave us contains information about the 22µH choke. The schematic recommends a 22µH choke with a current rating of 4.3A.

Also, why not having a look into the datasheet of TAS5760M-Q1?

Hi kai

In schematic updated as per datasheet recommendation , i want to guidelines for selecting Inductor Like what is minimum current / internal resistance , Frequency .

Also want is peak current when device is active mode?

Hi Kai

Please confirm shall we use this inductor audio filter path

VLS6045EX-100M

Pls check and confirm its very urgent

Hi Nagaraj,

Take a look at the following app note. It explains some selection criteria.

Regarding the EVM, choose the EVM below

Hi Nagaraj,

the choke you have chosen is only 10µH. But you will need 22µH.

Hi Nagaraj again,

forgot this: 10W across 8R gives 1.2Aeff, or 1.6Ap. So, to have some safety margin, take a choke with a current rating of at least 3A. But take care, if you will replace the 8R speaker by a 4R speaker later you would need a choke with a higher current rating (4.3A).
