In my application I'm using a 12 bit DAC (AD5621). Because of the bad signal integrity of the SPI I cannot go higher than 12 KHz SPI Clock.
Unfortunately the DAC does not chance his output value. It always stays at 0V. I'm asking myself if there is a minimum spi clock frequency the DAC needs to work.
Thank you very much.
minimum spi clock frequency instead of minimum spi clock
