TAS5805M: TAS5805M - Setting I2S Format

C%20K%20Ong

Part Number: TAS5805M

Hi,

When I set register 0x33 = 0x02 (24-bit), 0x34 = 0x00. Where is the most significant bit of the audio data located (or how many BCK) from edge of the LRCK?

Hello CK,

With you current configuration of

Reg 0x34=00, 0 BCK (no offset).

For further details please see Page 54 of the datasheet.

All the best,

Carolina

Dear Carolina,

The I2S setting is the most confusing setting in all TI Amp.

When I set 0x34=00 will I be getting I2S format as followed:

Hello CK,

Yes you will get that I2S format, the offset available for SAP_CTRL2 register setting is more for TDM purposes.

All the best,

Carolina
