LPC1758 using external ADC or Mux existing ADC, how to i get an interrupt on "done" ?

I need 4 ADC in my project, my dev board has only 3 available ADCs. So from what i understand the correct way to use ADC is to have an interrupt that tell me when the ADC is DONE. If i use external serial ADC (I2C for example), how will i get that interrupt ? or maybe to MUX the existing ADC, and than i have basically the same question.

thanks Dan

I haven't used external ADCs myself, but I expect most of them to have an interrupt output, which you can connect to your microcontroller and use as interrupt input.
