Hello,
We are looking at the DDC114 for measuring ouput pulses of a laser. Pulses are 150ns wide with peak power of 3000W witha low duty cycle (2KHz). We need to measure energy to 1% on each pulse.
We are thinking of using a switched integrator with a window on either side of the pulse since there is plenty of time to sample the pulse.
The DDC112/114 might be a good fit, but I'm not entirely sure about the transient response characteristics. The only parameter seems to be slew rate but I'm not positive how to evaluate the device for speed performance. My first assumption is that over the course of the 150ns pulse (assuming it's square-ish) that the rate of charge of the capacitor simply can't exceed the slew rate and otherwise would be fine?
Do you think this would work?
Thanks,
J
