Hello everyone, I have a question about precision DACs. I got homework about find 16bit DAC with output update rate slightly higher than 4MHz, If I count well, that mean I need less than 1/4M = 250ns settling time. I'm still finding 10 times faster or 100 times slower. What am I doing wrong ? benefits are paralell inputs instead of SPI or at least quad SPI. Thank you all very much for help!
