Hi Kevin, Thank you for your response. 1. Actually, now output is coming correctly. Even spike is also not coming on triangular waveform. There was a issue with chip select signal timing. Before it was like, the amount of low time of chipselect signal was greater than amount of low time of Write signal. I reduced the amount of low time of chipselect signal to the time of Write signal. Issue got solved. The data will be latched to DAC register at the positive edge of chipselect signal. But in our microcontroller(XMC4800), the data will be available even after WR signal goes high. So when chip select signal is low even after WR signal goes high proper data will be available on data bus. But output is not coming for this case. Spikes will come on certain points. 2. If I introduce a delay of certain milliseconds while incrementing every bit (0 to 4095), on triangular waveform I should be able to see step like behaviour. For the amount of time the delay is introduced same voltage has to come. But I did not observe steps. What could be the cause for this? Thank You
