TAS2560: Question of TAS2560 DAC Gain

Wayne Chen (Audio AE)

Part Number: TAS2560

Hi Sirs,

Would you pls advise the TAS2560' maximum DAC gain 16.4dB or 15dB? We saw 16,4dB in test condition while PPC3 GUI and register map shows 15dB max.
If 16.4dB is the specification, how to program the TAS2560 device to achieve 16.4dB gain?

Thank you and Best regards,

Hi Wayne,

I was researching and the DAC_GAIN is only for the analog circuit, so these values are correct in that fashion. The digital circuit adds a constant 1.4 dB for a maximum total of 16.4 dB.
