I am trying to measure the glitch from the BP-DAC11001EVM. I set the software to LDAC, and I'm driving the LDAC with a separate microcontroller. This way I can cue up the code I want to write in software, and then trigger the LDAC and simultaneously measure the glitch.
This is what I measure when going from 0x7FFFF to 0x80000:
The magnitude is much less than the datasheet spec (5 mV) which is nice, but it takes FOREVER to reach the final value. Much longer than the settling time spec of 1 uS. Am I doing something wrong?
