Dear All,

I am new to the STM32 world and I would like to check it is possible to connect Analog Devices DAC AD5443 using SPI to the STM32F429. DAC has a SPI running up to 50 Mhz and STM32 just to 45Mhz, but except this, the SPI timing diagram of both devices seems to be compatible. Do you agree? Dou you see any potencial problem on this subjet? Any comment will be wellcome.

Thanks in advance,

Joaquin.

Those will work together. You'll be limited to the smaller of the two max data rates, of course.
