Hello,I'm finding a DA satifing the follow factors:

a) can garantee the width of signal is 500ns~20us,and the repetition rate  of 10K~50KHz

b) can garantee the amplitude of the signal is 0V~4V 

Please help me,thank you!

    If you are welcome to the idea of using multiple DACs, then you can check AD5449, which is a 2-Channel Multiplying DAC capable of 2.47 MSPS update rate, which is around 405 nS between each frame sent.

    You will also be needing a transimpedance amplifier at the outputs.

    If you still need higher update rates, you may check High-Speed DAC community here in EZ.
