help for the choice of the DA!!

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!

    Do you really intend to create pulses going from 2V to a certain value, then back to 2V?

    What is the application of this circuit?

    You may consider using AD5676R which has 8 channels and can output 0 to 5V using a gain of 2.

    However, the fastest update period is around 870nS, and on top of that, you should also consider the slew rate for big voltage steps.
