Dear support team,
I want to know the state of ALL pins in reset state for ADAU1442 and ADAU1452.
Could you tell me about it,please?
I have information regarding the ADAU1442. In reset mode:
All LRCLK, BCLK and SDATA_IN pins are inputs, and each has an internal pullup of approximately 80 k ohms.
All SDATA_OUT pins are outputs and have no pullups pr pulldowns.
Please let me know if you need any more information.
This information is not something we normally put in the datasheet, so unfortunately I don't know the answer. I have asked the design team. Hopefully they will provide me with information soon.
This might also be something that can easily be tested on the evaluation board.
Thank you for your reply.
But,I need to get thease informations from ADI.
With regards to the ADAU1452, the digital I/O pins are high impedance when the \RESET pin is held low. All of the pins have weak internal pulls, the I2C (and \RESET) pins are pulled up and all other pins are pulled down.
I will answer about the ADAU1442 as soon as I can.
Thank you for information about ADAU1452.
I'm waiting to get same information about ADAU1442,too.
Could you tell me about status of ADAU1442,please?
I apologize for the delay in my response about the ADAU1442. I should have an answer for you very soon.
Thank you very much!!
