Circuit Eval-adau1701miniz
Hello. The EVAL-Adau1701miniz card uses Q2 to activate the writeback function. The Q2 base is connected to the power capacitor 5v. Thus, the function will be activated when the power supply voltage of the chip is << 3.3. Does WB really work? Are there any inaccuracies in the board documentation?
Hello Andrei,
You're absolutely right -- the ADAU1701MINIZ's writeback trigger has known issues. Please see:
