    I am using LTspice to help me design a circuit board. On my board, I need a DAC where I input through a parallel port and output an analog response. The DAC will drive an op amp to generate the required voltage levels (0-30v). I am more concerned with getting a sharp transition time then generating a precise voltage. I need about 5 different voltages.
    Many companies make high speed DACs including Linear Technology but I am having trouble finding spice models for DACs.
    I simply want to toggle some of the MSBs of the DAC and find the transition times. Where can one find spice models for these devices?
