TAS5760M-Q1: TAS5720 / TAS5720 detection

Fabiano De Angeli
Prodigy 10 points
Part Number: TAS5760M-Q1

Tool/software:

I need to distinguish if the onboard amplifier is the TAS5720 or the TAS5760.
Is it possible to distinguish the TAS5720 from the TAS5760 via I2C?
The "Device Identification" register value is 0x00 for both devices.
Is it possible to distinguish by reading the "Analog Control" register?
For this register the default value for the TAS5760 is 0x51; the default value for the TAS5720 is 0xD1 (my datasheet reports 0x51 but I think it is an error).
Is it a reliable approach?

Thanks

Fabiano

    Hi Fabiano

     I'm afraid it is indeed not possible to distinguish from I2C. Even the register analog control, the power up default value is the same, just the TAS5720 must manually set to D1. Can't be used for your purpose.
