Hi, I am working with a legacy circuit in which the AD5390's DCEN/AD1 input was not tied either high or low. The design was suppose to operate in standalone mode for an SPI bus. Is there any guarantee that the AD5390 will operate in SPI standalone mode?
Hi Sal,
You might still have problems during a write sequence if the DCEN is accidentally high. If there are cases wherein you might have added some clock signals the data will ripple out of the shift…
