I am designing a camera that is powered by a 5 V DC power line. I need to evaluate the peak power consumption of the device during image capture. At a pixel clock period of 40 microseconds I expect that I can do this with a power monitoring rate of 10 kHz. The camera has an average power consumbtion between 1 and 2 W.
I found the ADM1293 power monitoring IC. The sampling rate is not explicitly stated, but with the clock rate of 400 kHz i expect it should be sufficient.
Am I correct or would I need something faster?
Is this circuit maybe too much for my purpose?
