Hi

Just want to clarify datasheet description details.

https://www.analog.com/media/en/technical-documentation/data-sheets/ADAU1463-1467.pdf

Connecting Pin 37 to logic high (IOVDD) initiates a self boot operation the next time there is a rising edge on Pin 24 (RESET).

> Wondering this should be Pin 42?

Regards,

Tomoto

Hello,

You are correct. The data sheet confuses Pin 42 (Selfboot) with Pin 37 (IOVdd). For example, in the schematic for the Eval-ADAU1467Z board, we see its Selfboot DIP switch selecting a high or low for pin 42 (referenced on another page of the schematic).

Best regards,

Bob

Hi

I think it's better to have an errata sheet for the Rev.A datasheet?
