ADU1446 sleep mode

Hi!

 

We have a custom board with a ADAU1446 SigmaDSP (selfboot from EEPROM), a AD1939 CODEC and a PIC microcontroller.

-Is there any possibility to run the DSP in a sleep mode (less then 40mA) when audio is missing for some defined time and wake up on audio detect?

We could disable the voltage regulator of the ADAU1446, but then we need another device for the audio detection...

 

Best regards,
