Hi Martinez, Welcome to E2E and thank you for your query. The gap between two SPI frames is defined by t-WH(FS) i.e. 20ns. That means you can ideally write the frames with a minimum 20ns gap between adjacent frames. However, your actual output for each channel will take a larger time to settle. To answer your specific question; yes, you can update multiple channels without waiting for the DAC outputs to settle provided you are maintaining the minimum HIGH time for FS. When you repeat, you need to respect the settling time for each channel to get the desired step. Hope that answers your question. Regards, Uttam Sahu Applications Engineer, Precision DACs
