TAS5766M: Question of Full Scale of the I2S SDOUT of TAS5766 and TAS5825

Wayne Chen (ex FAE)

Part Number: TAS5766M

Hi Sirs,

Would you pls advise the full scale output of the TAS5766 and TAS5825's SDOUT of Post Processing? My customer would like to know the relationship between Class-D's Vout vs SDOT's dBFS of the TAS5766 and TAS5825.

Thank you and Best regards,

Hi Wayne,

For TAS5825 & TAS5766, Sdout is the output of internal DSP. Digital output * Analog output = Vout. Hence Vout depends on the analog output settings too. But TAS5825's full scale is 29.5V while TAS5766M is 28.28V.

TAS5825: Please refer to table 2 of : www.ti.com/.../slaa894.pdf

As to TAS5766, please refer to table 7 and related contents below:
