I am wondering about the max. update rate for the AD5422.
In the data sheet, I con find a lot of timings for the SPI-Interface.
24 bits have to be transmitted to the DAC with up to 30MHz, and LATCH has to be low for min. 40ns.
I can't find any other restrictions like "min. Data-to-data time".
Does this mean that I can update the AD5422 with up to 1.26Msps?
By the way, Does anybody know the time between the rising edge of LATCH and the AD5422 Iout current starting to change?
I am looking forward to your answers.
