Other Parts Discussed in Thread: DAC63002,
Tool/software:
We want to control an external DAC (DAC63002) through SPI communication of MSP430F5638.
However, unfortunately, we found that the DAC output intermittently turned off and then returned to normal output.
So we checked each SPI signal and found that the SYNC signal was completely turned off for one period intermittently.
As shown in the picture below, when the DAC outputs normally, the SYNC signal is low for only a short time during the SDI signal is input, and then returns to the high state.
However, we confirmed that the SYNC signal would intermittently become low throughout one period, and that the DAC out would be completely turned off exactly in the next period.
Could someone please tell us the possible cause for this phenomenon where the SYNC signal is turned off for one period?
